Allow multiple account (Sync ID) and selective folder to sync

[test-0-zero]

I think it’s a good idea to have multiple accounts and the ability to select folders to sync.

That way you can share whatever you want with whoever you want.

It would be the perfect service.

Thanks a lot.

Hi, we are currently using floccus (https://github.com/floccusaddon/floccus) at our team at work (only 15 persons), but having issues with it. We are testing now xbrowsersync as an alternative, and selective folder sync and multiple accounts (syncing the same bookmarks) would be very nice as no one in our time wants to share their whole bookmarks.
