GUI:
* adapt to taller panels
* adapt to vertical panels
* look at code for cd player applet for adaptation example
* auto-expand to take up available space?
* is the logo needed?  replace it with just a handle?

Moosic:
* allow specifying which server to connect to
* loop mode toggle menu item in right click menu
* same thing for queue advancement
* playlist editing (or maybe just launch Daniel's moosic GUI?)

Development:
* make adding configuration options easier
  (like it is easy to add buttons & menu entries)
