On profile screen, there is an indicator of server in upper right. It's not the server I wish to use, and I am unable to change it. In my case, that server has a single library, and it's a large music library (nearly 100k tracks). The main screen just sits at a "spinning butthole", presumably because of the number of items in the library.

So I think two problems: 1) needs to be a way to select server and 2) should handle larger libraries
