Time for some progress updates!
There is now a system menu:

Backups can now be cancelled. Updates can also be cancelled. Yes, the layout is bit off here but it will be fixed before the release:
Also, we have reworked the email handling for apps a bit to support some use cases. Currently, apps are create a mailbox of their own and one cannot easily access these mailboxes (if someone replied to the email). We have fixed this so that apps can now be associated with any existing mailbox. By default, an address is auto-generated for the app. You can then change this to an existing mailbox which you can access using your credentials. It's also possible now to share the mailbox name across apps.
