I would seriously love #1 and #2. I would love to rate tracks and edit my beatport link playlists more easily. Cant even give a track stars. Adding tracks to Beatport Link playlists and even making playlists in RB would be awesome!
#3 is a huge problem for me. Often? more like every track. I have a support ticket that got a reply a few days ago. Their engineering team replicated the issue and is investigating it further. I'm having this issue with different computers and accounts. Really odd if you ask me. A fix for this I discovered was going back to RB 5.6.1. (not working with 5.8, and 5.7 is unavailable). But going to 5.6, I lose all the new beatport link features :(
So its definitely a RB6 issue. Soundcloud Go doesn't have this issue in RB6.
Never tried #4, so ill see if I have that issue.
