Huge +1 here. I have a couple folders and am not interested in adding more. This is pure UI clutter. At the very least, can it be buried inside of the advanced options? Please give us a way to turn it off!
My two Windows 8.1 machines won't sync with each other either (note the right side of the image): I generated fresh sync keys for all of my shares via the preferences dropdown which changed from longer keys to the newer shorter ones but that didn't help. As far as I know everything is normal files and folders inside of the my sync folders. Should I email debug logs? EDIT: Well it took a while but it's syncing some data. EDIT #2: It stopped after syncing about half the missing data. Dang. Still out of sync.
