Hello, I don't understand the initial problem nor issue #11. Could you explain what you're trying to solve, and what this commit is supposed to do?

• When the corresponding key is pressed and this program is in background,
  its window is brought to the front.
• When the corresponding key is pressed and this program is already at the
  front, the window would be minimized. < -------------------------------------------- see here
• When the corresponding key is pressed and the program isn't launched yet,
  it is spawned by running the program in the command property.

This would be the desired behavior for me as well.

Sorry for the late reply.

OK, I tried it and it's nice.

Could you clean the commit? (remove all the commented code, let → const, code style and whitespaces, 2-space indentation, remove get_active_window() if global.display.focus_window should be used everywhere, etc.)

I don't use gnome any more ,you can just merge it and clean it by youself.
