background folder retention tasks conflict with offline sync
I have a lot of folders which I have the retention set to delete messages older than 30 days.
If these tasks are running in the background when I do a "Download/Sync Now..." to retrieve messages for offline use then I get a series of dialogs "The operation failed because another operation is using the folder. Please wait for that operation to finish and then try again"
These dialogs are infuriating, download/sync should intelligently wait or skip folders on which other tasks are taking place.

Thunderbird can not add or modify a folder (file) more than one tread/operation at a time.
Given you are using IMAP. Push notifications should be enabled on almost every mail server by now, so need to press the get button should be very limited really.
I have push, this is fine for Inbox.
It is not fine for emails that are moved to folders by server-side rules.
My complaint: "download/sync should intelligently wait or skip folders on which other tasks are taking place." still is a valid feature request. If folder modifications need to be single threaded then it is Thunderbirds responsibillity to act single-threaded on folders, and not produce errors when it makes the mistake of doing so.
