// Create a vertical view for high-res versions of all the image links you can see.
// This includes all pages from multi-image submissions, where those exist.
// Individual images (or whole submissions) can be removed with one click.
// Each image is also a link to that image.
// User options:
var default_size = "short"; // Choices: short, fit_width, fit_height, fit_window, full.
var new_image_rate = 50; // Milliseconds between loading images. E.g. 10 for instant, 200 for gradual.
var fetch_rate = 250; // Slower rate for fetching than for loading images, to avoid rate-limiting.
var top_to_bottom = false; // Default order. True: as seen on the page. False: reversed, which is usually chronological.
var keyboard_controls = true; // (We don't actually have keyboard controls yet.)
// What I have so far could easily replace Pixiv Fixiv's current code. The spans with this.parentElement.remove() stuff, anyway; we know the image count beforehand.
// For both, I'd like to stretch a thumbnail behind an image as it's loading. I'd need non-square thumbs. Or at least I'd really prefer them.
// I guess style=backgroundWhatever:that.src? I keep adding and removing this -> that for some damn reason.
// I could trivially turn this into a Pixiv Fixiv replacement - right? All I need is any image URL. No JSON shenanigans.
// Change the BG color to something dark. (Ego says #324.)
// This accidentally ignores muted images - I'm calling that a feature.
// Ugoira animations get a spot, but don't load an image. Semi-feature. Deserves better handling and indication.
// This script suggests a generic solution to Twitter nonsense: replace tweet divs with their media. Break classes and IDs so their infinite-scrolling JS can't remove them. No worries about their stupid random class names, since we'd just parent.parent.parent and then .replace().
// Also I could probably just .remove() the sidebar bullshit.
// Maybe ctrl+z instead of a per-image 're-show' button? Stick per-image-group IDs on a list, first in last out, as they're removed.
// And use a damn dark mode already!
// Buttons for forward/back? Floating over top, maybe. scrollTo stuff. Ech, but it has to update as you manually scroll down, so prev/next are at least consistently relative.
// Ideally the focus is somewhere in the middle of the screen, not like, one scanline of an image counts as being 'on' that image.
// Oh, file-extension issues in Universal Scraper don't apply here.
// Gelbooru is inconsistent about WebMs. Some resolve to images. Others are blank. Dunno which is better, but pick one.
// https://gelbooru.com/index.php?page=post&s=list&tags=rosiekawaii
// Still, address videos on Gelbooru. E.g. https://gelbooru.com/index.php?page=post&s=view&id=5614716&tags=rosiekawaii#dnr#&dnr
// https://img3.gelbooru.com/images/3c/23/3c2376210444f7a7da737b412c722faa.jpg
// https://img3.gelbooru.com//images/3c/23/3c2376210444f7a7da737b412c722faa.webm
// Totally doable. So how do I check for a file without just embedding videos? Ugh, might be beyond onload / onerror behavior.
// Orrrr I could check tags. Not reliable. Could be wrong. But would allow a <video> with onerror to fall back to images.
// Better idea: indicate that it's probably a video, and link to the page without #dnr&dnr. Use Eza's Image Glutton, folks.
// Obviously that's the Ugoira solution on Pixiv: "don't." So it should be how I handle Ugoiras now that they're broken-ish.
// Embedding videos is undesirable because it implies linking to them for download.
// This script is already rude on bandwidth - videos would make it a DDOS attack.
// Solution: show thumbnail, not linked. (To avoid DownThemAll grabbing the thumbnail.) I guess link it to the page. Big _new target.
// Other Mastodon instances? Pawoo.

// I am alarmingly close to forking this for Mastodon, doing @include *, and testing for e.g. h-cite / h-entry.
// I don't want to @include * in general - this is not a general-purpose script.
// Even a fetch-based version would only be as flexible as Image Glutton.
// ... I've accidentally made this @include * friendly, by exclusively using button_delay_function.
// If it defaulted to false I could use this anywhere, and only specific switch-case / match domains would get better values.
// Or I could skip the interval entirely if button_delay_function remains at a default null.
// (Probably better to do so if gather_items remains at a default null.)

// Youhate.us? Down.
// https://thehentaiworld.com/tag/romulo-mancin/page/2/ ? Images and manga.
// CSS-only? Absurd tangent, but GreasyFork now lists CSS userscripts. It's probably possible to replace thumbnails on gallery websites with RegEx'd full-size versions, and fallbacks for each file extension. And obviously I think you can insert a line-break ::after each image and make them full-size or max-width / max-height. But yeesh.
// Might use thumbnails of first image as scroll-into-view links at the top of the page.
// Maybe with Xs on each to remove things from there as well? Questionable.
// Middle-click behavior (since they're not links) wouldn't interfere, but wouldn't be discoverable.
// Probing is possible without thumbnails - just onLoad( classList add "ready" ). Same results, but slower. Meh.
// Spent a while agonizing over performance vis-a-vis live HTMLCollections vs. querySelector, and found out it super doesn't matter.
// Setting up getElements and then only checking the first one has approximately zero impact on a modern PC.
// And the impact of setInterval seems to be approximately dick-all, so long as the timeout isn't zero or effectively zero.
// The upshot is that I set the timer to 10 ms and pages just -fly.- The "swallow gallery" button works immediately. Images load instantly.
// The latter is a mild concern, because sites might notice. An ideal server interaction looks just like opening a bunch of pages.
// Might move image count to the controls area.
// Its text already implies "image size" and "image order." But mostly I'm bugged that it doesn't line up with other text.
// Thematically, the image-size controls should probably be blue. Meh. They're distinct enough for not being grey.
// Consistent color is difficult. I want my clearly red and green reload / remove arrows. But there's little indication of which buttons affect a submission, a single image, the whole page, or simply your position on the page. I tried several janky attempts and figured it's best if engineers don't design interfaces. Plain grey with function-indicative color on-hover is just fine. The only buttons colored by default are the image controls, which are labeled... sort of.
// Abandon thoughts of up-arrow on bottom submission remover. It'd conflict with... actually it might perfetly fit what remove-and-advance conveys.
// Maybe the issue here is overloading what 'X' means. No idea what else I'd use for 'nuke submission.'
// It is annoyingly easy to get caught clicking remove-and-advance instead of just 'advance.'
// The button snaps into place under your cursor if you're submission-aligned and hit 'next image.'
// It's a problem mostly because the apparent result is the same - we scroll clean past the removed image.
// I could move html+="<text>" into actual DOM stuff by doing replacement_html = document.createElement( 'html' ).
// Main reason not to: it's so much more verbose. Even if I moved append_new_element to the top and used that: text is concise.
// To do:
// Keyboard controls for navigation, removal, and remove-and-advance.
// Put alt/title (onhover) text on size / order buttons?
// Genuine bugs:
// https://www.pixiv.net/user/55117629/series/87453?p=2 - gets everything but the manga. Different page format.
// Ugoira submissions display a big floating X, because those belong to the image-extension-trying block, not to each self-removing image.
// Ahh, it's because next_image would try _p0 and fail. This rewrite assumes the first image works. Maybe do cleanup in the interval?
// Navigation controls make this more of an issue. At least they tuck under the next image's controls, so they're merely unsightly.
// Dead images and possibly thumbnails take up horizontal space and cause slight movements while loading.
// Spinners don't spin on Baraa. (Might be intractable.)
// Changes since last version:
// Refactored createElement / set attributes / appendChild pattern into append_new_element.
// Refactored per-submission stuff to use that too.
// Elided object ? object.property : null into a DRY function, safely_return_property. Refactored accordingly.
// Realized most sites have previous / next links that make reasoning about URLs pointless. Safely grabbed those.
// Replaced hideous probe-try parentElement.parentElement.parentElement chain with closest().
// Refactored scrub_extensions to insert '%format' instead of trimming.
// This lets me finally get rid of probe_followup / image_followup, and it allows per-image keys instead of trimming them.
// Similarly used '%number' for automatic_pagination.
// Fixed missing images_spinner (the orange one) on FurAffinity. (z-index issue.)
// Same deal on Rule34.xxx, but with higher z-index numbers.
// Fixed misaligned spinners on Danbooru. (box-sizing issue.) The blue one's still a little skinny for some damn reason.
// Spinners on Baraag don't spin, but at least they show up.
// Golfed the spinner interval. At this point I'm aggressively reclaiming line count.
// Elided spinner_interval global variables altogether. Just getElementsByClassName once per second.
// Made force_css (now enforce_style) test-based and therefore automatic.
