Better visual cueing of why StenoTray gave a suggestion

I appreciate the colorization of left and right, but I've found the vowel background coloring a bit puzzling. It would make more sense to me if the highlighting was driven by what caused StenoTray to recommend a stroke for me. So if it is because the stroke is a prefix for a longer stroke, highlight the stroke, if it's because I'm finger spelling a word, highlight the word.

A related thing you could do is have stroke based and word based suggestions separated. I don't know if that would make it easier or harder to find, but I definitely feel that I often see suggestion I don't like because I was expecting the other style of suggestion.

This is also important because if I'm being shown how to brief a word, this is useful for the next time I'm stroking, but not as I'm stroking right now.
