[Feature Request] Handle workspaces independantly by monitor

[ahshabbir]

Firstly, thank you so much for this extension! It really makes work-spaces more usable for multiple monitors, so this has been indispensable to my productivity. One thing that would be nice to have is to allow for an option to handle workspaces across monitors independently. For example, on my first monitor, I can be on workspace 1 while my second monitor can be on workspace 2. Ideally, I could switch between each workspace on each monitor without affecting the others. I'll try to look at the code this week and try and see if I can work something out, and will submit a pull request if I come up with something, though my project development skills are kind of week at the moment.
