//LATER TODO maybe improve the json export functionality using API data like x/favorites-scrape. For now the Extended layout is adequate. Magnet links can be generated using the API data as well.

//Top text box inspiration and its code from http://userscripts-mirror.org/scripts/show/173553. But this one won't have an import feature like that one.
//Using he.js for he.js purposes.
//Using GM_webextPref for the preferences menu. Many thanks to the author "eight" for the library.

Trying to stay compatible with the dnsev-h' JSON format.
Using gallery_info_full but obviously a ton of data is missing. Just compare the output.
Tags might be missing their alternative spellings ("hanafuda sakurano | hanafuda sakura" will only have "hanafuda sakurano")
