While editing—Tabs uploaded/not uploaded indicator

While editing files, how about a red dot next to the file name on the tab if the file has changed but has not been uploaded? And a green dot when it has been uploaded ( or is same as version on the server).

Seems like that would be an easy one and very helpful at a glance while working on files while in a distracting environment.

Yes, some of us don't have the luxury of a nice, quiet, undistracted development environment 😉
