I can do without syntax editing (would be nice though), code suggestions etc, all I ask is that you add multiple undo's to the internal editor. Currently you only get one using Ctrl-z but most of the time it isn't enough. I've lost count of the times I've wanted to go back to an earlier edit and have to spend hours instead trying to recreate my earlier code. I know I should do frequent backups but sometimes I forget.
Please add this. I will be most grateful.
