Not something I want to do, but something I have to do, since Microsoft is dropping support for Xamarin...

Add an option to display the radicals for each Kanji in different colors

Sometimes, I get a kanji wrong because i accidentally tap the screen somewhere before i even start drawing, etc. In cases like that, it would be good if I could:

 - mark as a flubbed input

 - retry without recording a success or failure, and without revealing the kanji (as this would tell me the answer)

Currently, the only option when this happens is to mark the answer as incorrect, as the fact that i can see the kanji and didn’t draw it means i can’t just assume i’d have gotten it right.

Eg. should be able to select a bunch at once and marked them as "known" or "unknown"
