Feature request: Display which mapping are running

[TherinS]

I often have input-remapper running keymaps for my gameboard (currently a Delux T9) and a mouse that has extra buttons. The T9 is mapped for various games and I use a specific button on the mouse to activate push-to-talk in Mumble. When I look at the GUI of input-remapper in the Devices window, I cannot tell at a quick glance which devices are currently being used.

Additionally, I have found that the position of the devices attached to my computer changes on that window between sessions so I cannot click the same spot each time for a specific device. It would be easier to tell which one currently has a running map if there were a check mark or other indicator like a shaded window to show which has an active map.
