I would like to see an additional setting in DeltaChat - suggested for the section for “IMAP folder handling” - for “Synchronize DeltaChat folder”. This would automatically download any missing DC messages from the server to the device as well as delete any messages from the device that have been deleted from the server perhaps done on another device.
When this setting is disabled DC would function as today, when enabled it would allow the user to keep all his/her devices synchronized automatically, ie messages missing/deleted/update read status.
What do you think? This is the main shortcoming of DC today from my perspective.
