Where there's a will, there's a way! Now that you are in, do keep us posted with any feedback. There's some issues we know of, and others that we're learning about thanks to community feedback (eg problem with display order of long starred playlists - currently being worked on).
We're currently not offering a high-bitrate option, and unfortunately I can't commit to when it will be coming although it is something that we're talking about for the future. I'm happy to hear you enjoy the web interface though!
