Beonex Launcher is for you. Beonex Launcher (BeOL for short, spoken B-O-L) has the options you will probably want and need, but no more. It's advantage is that it's lean, trying to do its job, without distracting you from your work.

BeOL is still in development, but you can get test versions for Linux already.
