Hello.
I don't know what are the rules for 1.0 branch but I would like to propose to backport this change to 1.0 branch:
Display full quota information in popup (#1485769, #1486604)
http://trac.roundcube.net/changeset/c5f06896d/github
I'm constantly getting reports of users confused about how quota is displayed by roundcube. It's quite small change and should be safe for 1.0.x.
