Great addon and idea, but the sync is a complete sh*t show. When deleting containers, they just somehow reappear, and if likely you'll end up with TWO, since it seems to restore the one you deleted and then pull one from the sync. In short, the Sync feature is completely useless, and have left me with at least 5 duplicates of every container I tried to delete. Can you PLEASE fix this? And there's no way to purge what's stored on the cloud.
