Better support for Jinmeiyou kanji
A handful of jinmeiyou kanji aren't used in any actual words (making them not currently supported). And a lot of the ones that are are so rare we shouldn't be using them as prompts. It'd be better to use names for prompts instead, the way they're actually used.
Some examples:
