I started using TO (from TabCloud, which is also cumbersome to save/sync) recently, and am finding it's just too much of a hassle to have to click TO Options, Backup Tab, find the most recent one, Click View, then drag tree root to TO Main Tab root. Actually, it's much more than that that you have to do to sync, you also have to first delete the tree in the TO Main Tab, so you don't have duplicates. Seems like this could be done automatically. Throw away all backups except the latest (after all, we have chrome history available to us for finding old pages), update the backup in the background as you work, and do all the steps above automatically when Chrome opens.
