The answers to those questions should already be in a new section of the Mail manual page: Restore a mailbox folder from a backup. Please let me know if the information is unclear or incomplete.
To clarify:
- Only entire folders (with their contents) can be restored.
- The restoration always places the folder under a special location, the “Restored folder,” which is created if necessary. IMAP users can then manage the restored content as they see fit, such as searching for specific messages or removing the “Restored folder” after reviewing its contents.
The same approach applies to restoring Share contents in the Samba File Server application: Restore File Server from Backup, with a main difference: you can select and restore individual files too.

There is an ongoing discussion in the Bug category, and I filed a related bug report yesterday. Let’s continue the conversation here: App install via Software Center not possible.
