Subject: gui: Remember menu position.
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=b94faafa111dbec1b5cc45fb588f9258b4ca5abc;p=gsu.git

gui: Remember menu position.

That's generally the expected behaviour, and it's not too hard to
implement. We let _gsu_menu() take an additional argument for the
default item and maintain its value in _browse().
