Here's another addition to my GE wishlist - improved stability for the existing code editor.
As of now, the code editor crashes GE if too many characters are added on a single line. Also, code following the crash is not recoverable at times.
It would also be nice if the code editor did not get "stuck" while typing. Sometimes, even while typing things into it, nothing displays on the screen, although I noticed I have to press an extra backspace for every character I typed in to go back to where I left off. Deleting the last visible character with backspace sometimes makes it "unstuck" again. The same issue occurs while copy-pasting code - only a part of the selected code is pasted while the rest goes missing.
The mouse cursor also sometimes does not go to the place I click on. Closing and restarting the code editor fixes this as of now.
A better font-background combination would be nice too. The current grey background makes it a little difficult to read font on screens with low contrast. Maybe a white background with dark fonts or better yet, a black background with light fonts (best suited for the existing font colour scheme) would be best. Black backgrounds reduce eye strain and save electricity too.
