//
// FEATURES
// - Use A/D or left/right arrow keys to navigate back and forward instead of clicking pagination buttons!
// - Minimally supports browse and search page types.
// - Extended page type support is spotty and may include user uploads/favorites and more.
// - Somewhat intelligent behavior!
// - Avoids navigation when user has input fields focused.
// - Avoids inappropriate back navigation on first pages, homepages, etc.
//
//
// CHANGELOG
// v3.4 Add A/D navigational keybind alternatives for 60% keyboard users
// v3.3 Add support for rule34vault.com, rule34.xyz, rule34.world, furry34.com
// v3.2 Various improvements
// - Convert remaining URIs matched by regex to globular
// - Add support for InkBunny user gallery pages
// - Fix browser-native key events being caught and suppressed (e.g. alt+arrow)
// v3.1 Various improvements
// - Auto-detect sites running booru-on-rails and derivatives
// - Move to globular URI matching for more sites
// - Support more pages across already supported sites
// - Add in-code URI evaluation for enhanced exclusion logic e.g. zerochan post pages
// v3.0.1 Bugfixes, and improvements to Minitokyo handling
// v3.0 Add support for booru.eu
// v2.6 Add support for minitokyo.net, inkbunny.net, and hypnohub.net
// v2.4 Add support for derpibooru.org, twibooru.org, and manebooru.art
// v2.3 Add support for tbib.org, safebooru.org, xbooru.com, realbooru.com, and booru.org
// v2.2 Add support for zerochan.net, anime-pictures.net, konachan.net, and kusomanka.com
// v2.1 Add support for rule34.us and gelbooru.com
// v2.0 Add support for yande.re
// v1.0 Initial release with support for rule34.xxx
//
//
// TODO
// - Additional site support:
// - Weasyl.com, FurAffinity.net, and Hentai-Foundry.com
// - rule34.us needs special handling for user favorites: ?page=1 doesn't work and must be removed.
// - rule34.xxx comment list page
// https://rule34.xxx/index.php?page=comment&s=user&user=* (pid offset of 15)
// - Add 'last page' detection logic to prevent inappropriate forward navigation.
// - Briefly change the cursor to visually indicate when a requested nav event fails or is rejected.
