For a second I thought it is a GUI for editing *hardware* keyboard layout automagically, by assigning symbols to all 4 layers of it, and I must say it made me happy, even though like MT, I edited it by hand, long time ago.

Although, character map is not less "cool" by any means! Installing it now, and for sure I'm gona do a xbindkeys bind to bring it up by key combination, from hardware keyboard itself. Awesome work, thank you!
