Since I’ve burned many kanji and words long ago, I made a userscript so I can quickly check if I have forgotten already burned kanji and vocabulary or not. Originally I made this script just for myself but maybe it’s useful for some of you, too. You can install it from here:
The script works on the levels-pages as well as the radicals, kanji and vocabulary levels-pages.
The script creates 3 buttons on the side which let you hide all kanji (and Japanese words in the vocab section), kana, or meanings or any combination of them. By hovering over an item the hidden parts will be shown. It’s a bit like flash cards.
A fourth button is only displayed if there are not yet burned radicals/kanji/vocabulary on this particular level. To not break the srs system all not yet burned radicals/kanji/vocabulary will be hidden from start but will be displayed be clicking the fourth button.
I tried to make it possible to resurrect an item directly on the level-page (without having to go to particular kanji or vocab-page) but I haven’t found a way to do it. So if someone has an idea how to integrate this feature, please share it! m(_ _)m Thank you!
