Bug 159274

I'm requesting a "tagging" feature. That is, you can right-click on a file in project explorer and tag it. The rules
would be open-ended. Could be color-coded or show an icon next to it to show that it's tagged, maybe even allow you to
add some comments.

This might be helpful if you have a huge project and you're thinking about committing or uploading some files the next
day or following week, and you have trouble remembering them all. This would be similiar to having favorites, but keep
you from having to switch panes quite so much. It would also allow notes you don't want to appear as documentation in
the code. But the important part of it is, you would have some visual cue that the file is more important than others.

This is useful if you're working on a project, but don't plan on uploading anything until you're done with everything.
And you're having trouble keeping track of all changes and want to quickly see which ones you want to upload. (This is
just one example scenario where tagging might be useful.)
