After the short outage of GMail just suffered, all my colored labels are gone. Oh what a PITA! I love all those colors in my window, and they help a lot focus on important stuff.
Ok, it's an extension in GMail Labs that enables them, but I hope they'll be restored (yeah, the same I had before) really soon! It would be very boring to redefine them all.
/me crossing fingers
UPDATE: colors are back now \o/
