Multi-monitor and empty-workspace detection

[Coffei]

Hi,

first of all thanks for the great extension!

I noticed the unused-workspace detection doesn't work well if you use multiple monitors and workspaces only on the primary one (which I believe is the default for Gnome). If you have some window on the non-primary monitor this plugin registers it on every workspace, thus every workspace is displayed as active.

I think the detection should only consider windows on the primary display in this case, would it be possible to change this behaviour? Perhaps it could be based on the gnome configuration (you can also span workspaces on all monitors) or it can be a config of the extension.

This definitely is a bug. I dont use multiple monitors myself so its not a big surprise I did not catch this. I cant promise I'll get a fix out soon but I encourage you try giving a go at fixing it yourself and open a PR :)

Ok, thanks. I have zero knowledge of Gnome extensions but this may be a good reason to learn. I'll see what I can do.

This is related to #8. The PR is basically what I wanted to do, unfortunately the solution has some issues as mentioned in the PR. I'll try to at least test the fix, since I am not sure I can improve it.

I actually did not even notice that PR because I am not notified of draft PRs (I think). Thanks for pointing it out to me :)
