Multi-monitor / Multi-window support

I have two monitors.  Right now (build 2190) opening a second window by dragging a tab and dropping creates a second window that is very much a lower-class citizen.  It doesn't have access to the project of the first window, which I think is the root issue for all other problems I've had.

I would love to have a second window open, without the sidebar, just for more code.

It sorta works right now, but the builder loses some references to the project/folder variables, if you close the second window after closing the primary window, subsequent launches open with no active project, and a few other little annoyances.

Thanks!
