I’ve been playing around with this, here are a couple of things that come to mind:
1. Would you consider making both color bars wider? They’re very narrow right now and sometimes it’s difficult to tell what color is being displayed in either of them. Perhaps you could color the input box with the type of word (pink or purple), and include a big red X and green O to the left and right (respectively) of the prompt to show when an answer is right or wrong.
2. Is it possible to only test vocab words, or maybe set up a toggle to switch between [Kanji+Vocab] and [Vocab Only]? My initial reaction is to say that it’s more important, when testing E->J, to test for whole vocab instead of individual kanji.
3. I think this is a bug. When I hit Enter before entering any text, as soon as I hit enter it immediately skips to the next word, no pause to see if I got the last word correct or not.
This is a fun tool, thanks for releasing it!
Edit: Here’s one I forgot to mention:
4. WK is awesome because you can activate just about everything via keyboard shortcuts. In that vein, is it possible to toggle the visibility of the correct answer via the F key (in keeping with WK hotkeys)?
