Before syncing, you can only see the folder name, not the content.
After syncing, there is no problem to identify the source. You can even change the synced local folder name. But the name changing is local only, you still see "Documents" on other devices, not "Documents_O_iMac".
I have several computers, NAS, phone, tablet to sync. But I don't need every folder to sync to all my devices.
And some I don't need to sync anymore, but I don't know which one to remove.
What I need is to be able to identify the folder before syncing.
Thanks
