First issue:
When skrittering in the non-dark theme, it can be really tough to see the words "simp" and "trad" at the top of the screen. I know that the "simp" shows up on the left and "trad" on the right, but sometimes I don't see anything at all and it's not very convenient. Please make those two words a bit darker for the next update.
Second issue:
It would be nice if there could be a place for word mnemonics on the app. I would actually rather have this than character mnmenonics.
