When viewing an email and then clicking the "Label as" button: Please sort the labels by usage: most used at the top!

Example of the current situation:
The first label I ever created is at the top, but that doesn't mean that I need it all the time. It was for a vacation years ago, so it would make sense to have that far at the bottom. I would prefer having the labels that I used most recently at the top, because maybe I want to label a bunch of mails with the same label.
