Most of my complaints are what everyone else has been saying. Mostly, there's no "Connect to IP" option which would be nice to connect to 127.0.0.1 though I imagine when LAN support is complete, it can be used for that, but it'd still be nice to have. Also in 800x600 (I play in a window while doing other stuff so I use a fairly low resolution), the menu items overlap the logo making them hard to read and just looks kind of ugly.
Then just the usual stuff. No sorting outside of the list view. No latency measurement or connectability status whatsoever. I didn't test extensively, though as in I just loaded it up, found out I couldn't connect to my own server and then uninstalled.
