robert: In this new version 0.9.7, I took out the Esc keybinding, with some reluctance. I'll have to learn not to hit Esc so often. I liked the symmetry of popping up the menu with Esc, then closing the menu with another tap of Esc. But now that Ctrl opens the menu, I don't mind it as much to not have Esc doing that. And I think consistency across apps is importatnt, too, so Esc reverts to the default FLTK behavior.
Juanito: Sorry I misunderstood. I have added the '%' above the icon when the battery is discharging.
