Autosaving Code Editor

I think it would be really useful if the code editor autosaved automatically after a period of time. It could be turned on and off in the settings, and the delay between saves could be configured.

A similar concept would be to auto save code before compiling. I've had a lot of problems wondering why I was still getting errors before realizing that I hadn't saved my code.

It's a relatively small change, but I think it would be incredibly useful.
