Would it be possible to display the CVS tag/branch that this file was checked out on, in the tab. (If HEAD, I guess omit)
The only other way to see the tag info is to open the cvs files view (takes some time to update) and try to locate your file in there, and that also takes some time.
Also, some times it is possible to forget you updated from a different branch, and now you check it in to the wrong branch.
The information is readily available without all that, so if you could just display it, that would be a great help!
