Report Are You Still Using Btsync 1.3.xx? in Sync General Discussion Posted October 30, 2014 I just upgraded from 1.3x to 1.4 on OSX. And I have to agree the new interface is horrible. The old one looked native. And even if it's more work to give each platform it's native interface, I think it's the way it should be done. There's a reason why each OS' interface is different. So each OS deserves a native application UI. Otherwise, the result is just ugly.
