I didn’t realize that gmail’s web interface was upgraded recently. I am a user of the gmail macros Greasemonkey script. It stopped working right around the time my Gmail offered its new IMAP enable functionality.
IMAP is nice and all, but if I had to choose, I’d choose to have my Greasemonkey script work. Luckily the script has been updated to support the new gmail web interface.

You have to go manually install the script update. So if you were using it and it just stopped working, go upgrade!
It is worth it just for the “e” to archive functionality. “l” to label is just a bonus.
