I usually have the same filenames for different project and sometimes have to work simultaneously on two or more /don't ask (:/. The problem is that there is no easy way of telling which file belongs to which project. Sure I can look on the title bar where the full path is but this is hard to notice and easy to forget when I quickly switch between files.

Color coding would be too much, but a simple distinction between files from active project /bold, different color or sth/ and others would suffice.

Optional automatic tab grouping is also some idea of solving the problem. We'd have sth like "project: file1 file2 file3 project2: file1 file2". It would take up more space but could be useful.

Anyone agree or has a better idea?

Hovering above the tab gives you the full path, perhaps that helps?

i like both options, can't they be implemented both
