The biggest problem I have with OS X 10.9 Mavericks is the replacement of color labels with tags. Tags are small dots of color next to the name of a file. A label is the coloring of the entire background of a filename. Labels are so much easier to see.
Sure, you can have more than one tag to a file. But you can only see three of them. And they get hidden when the filename length is long.
Ideally, TotalFinder would change the background color of a file name to match the top tag color of a file. This returns Finder Labels to us.
