Increase the code editor window!
It would sure be nice to have some real estate for editing code versus the tiny little window you provide. Further, please, oh please, support and implement tabs in the editor. Using spaces to help readability of code makes for a royal pain in the backside when editing. Come on - this window is very much reminiscent of a 90s code editor tool.
The current editor is soooo small... How the heck has this not been updated yet??
