[Feature Request] Use separate window for each server

[cinderblock]

I think it would help my workflows to have different windows for each server that I'm connected to.

Switching between work workspace and personal workspaces can get a little jarring, specifically for spatial memory of where the window is on my desktop.

This would also enable much better integration with "multiple desktop" features. For instance, I keep a separate "desktop" (on my one Windows 10 machine) for each personal project & work client. This makes it easier (for me) to keep the various clutters compartmentalized.

This feels like it should be easy to implement in Electron, especially since this is more like the webapp interface anyway.

I did see #699 but, as I see it, that is a different request
