These sound like good improvements. One of the things DLive did right is making the on-boarding of new users as easy as can be which I think is the right way to go, and Vimm should also focus on that as much as possible. Perhaps something like Dtube where Vimm has its own blockchain but is still connected to Steem so new users don't have to worry about the complexity of Steem if they don't want to while Steem users can continue to take advantage of Steem.

Another nice improvement would be the ability to set a thumbnail of a stream from the Vimm dashboard if the streamer wants to.

Now we just need more people to actually start watching streams on Vimm.
