Review for Move Mail Shortcuts by Bernhard
Rated 2 out of 5 stars
Glad to see there is an alternative to Archive This!
On my installations, however, the folder selection dropdown in the configuration is messed up - folders do not appear in order. Since I have >300 folders on my account and there is no search functionality, this severely limits the add-on's usability.
