I didn’t find a discussion about it yet:
I think a feature to change the synchronization order would be nice.
If you want to upload some bigger files they will be uploaded in ?random/date? order. It’s often useful to prioritize some files as you want to e.g. share them with someone. Or when you first connect to the server you want some folders to be synced first.
It would be nice to have for example a synchronization queue that you can interfere with by drag and drop
