Description

i really would like to have a menu part to configure proxy.

would be nice to have something allowing me to set those enviroment variables to every app that i launch, instead to open console, edit .bashrc, reopen console and launch the app again.

some of mine apps aren't on $PATH so i use the .desktop file to launch it.

i think that xfce could solve proxy too. kde and gnome does it as well, why not xfce?

if such feature already exists please ignore it and if possible tell me where do i do changes for proxy.
