Its a real little thing, but it has really made my day. Gmail just added the ability to COLOR your labels. This is great for me, it was getting really had to tell stuff apart having to read every label, now I can just glance and see what I have! I have all the important categories with bright bold labels and the junk will dull bland ones. Might be nice to use stars for the REALLY important ones, but I've yet to get into that habit.
Google does it again, they really try to make the customers happy, that's why I use them.
