Feature or enhancement

Because IDLE not good at text editing, I sometimes use another text editor to make text editing such as text replacement and refactoring while opening IDLE parallelly.

But when I go back to IDLE, the editor doesn't give any hints, and then on the next run, my text changes are overwritten.

So I add a feature that IDLE can detect whether the local file has changed and make a prompt, ask to refresh. or set file into unsaved state if not refreshed.
