- Fullscreen mode without menu bar. When I lock up MusicBee and someone else I don't know comes around, they tend to poke around and then cause some weird exceptions that I can't ever make. With no menu bar they will have less things to mess up (while I use a super-simplified panel setup), and unlocking can be made to use hotkey only so I won't worry about people trying all the passwords they can think of.
- Fullscreen mode with retractable player module. Just like in Firefox (and other internet browsers too I believe), pressing F11 gives you fullscreen with the controls, and then after seconds the controls collapse into the edge of screen. This can be useful when I want to maximize the area given to the library and/or playlists for visibility, like on a low-resolution large screen.
- Fullscreen mode without actually locking the entire computer. Sometimes I wish to just max out the area for information but still can ALT-TAB to other programs. This is also a bit like fullscreen in browsers where the entire screen is dedicated to what I'm looking at, and I won't have to go all the way back through the menus (or hotkeys) to get back to normal mode to check an IM message for instance.
- The above suggestions, at best should come at a tick-able choice like now

Keep up the good work MusicBee team!
