Currently, the folder list in the sidebar reads
INBOX
INBOX.Archive
INBOX.Drafts
INBOX.Sent
etc.
If would be nice if one could add a mapping for the folder names such that the display becomes
Inbox
Archive
Drafts
Sent
etc.
Maybe this setting can be integrated with the folders setting in accounts.conf. Also, the destination folders (archive, copy-to, default) have to be either aware of the mapping or the README should make it clear, that these settings reference the unmapped names.
And maybe abbreviating by default if a folder name is longer than
sidebar-width. First letter of every word in each path component between first and last?
