Can’t Copy, can’t set display spacing
I use a lot of private use area characters. This allows me to find them (unlike the unicode symbol keyboard i’m using), but not to copy them. that’s one star gone. The display allows changing display size, but also scales the character cells the same ratio, so I’m not able to see reasonably/readably large versions in any density. That’s star 2 gone. So… needed improvements: separate display grid size and character size, and make it possible to copy them characters.
