refold tools

this is a repo with language learning stuff:

• anki sentence mining card template
• yomichan user.js patch
• yomichan stuff
  (custom theme, sentence export/copy button plugin)

todo

• yomichan handwriting popup/input like in google translate using handwriting.js
• play audio for word in anki card template (download/stream/localStorage cache?)
• edit(/add?) generated readings in yomichan
• add dictionary items to yomichan
• blacklist dictionary items from affecting generated readings
• standalone yomichan server/api (yomichan is deprecated and will stop working once manifest v2 support is removed from chromium)

i'm not sure if i'll find the motivation or time to work on a standalone yomichan server, but if i do, it's the first thing on this list i'll likely attempt to implement as yomichan is being deprecated. existing hacks in this repo are focused primarily on improving my sentence mining workflow, but yomichan is primarily a lookup dictionary, with automatic anki card generation kind of shoehorned in. a rewritten frontend with separate modes for popup dictionary lookups, full dictionary lookups and sentence mining would be better.
