Ignore windows on other monitors

[TrickyRicky26]

I'm currently using your plugin with "Control maximized windows" and I have 2 monitors. It would be nice if you could configure one monitor that the plugin shows the title/buttons of and it would ignore windows on other monitors. Currently, I have to click in the window I want to close first and then close it with the buttons.
Similar features are implemented in most docks, if this helps find a way to implement the feature.

I agreed, this is one of the best plugins for XFCE, while works awesome on a single monitor when you have two it show always the windows that has the current focus doesn't matter in which screen is laid. This is really confused.

It would be really awesome if, for each instance of the plugin, you can set up: "work on screen 0"; "work on screen 1", etc...

Maybe this change is not so trivial as it appears, so my question is there any way to compile the plugin to work on a predefined screen, so I can compile two version of the same plugin one for the screen 0 and one for the screen 1.

Thanks in advance!
