### What should this feature add?

I'm sure this won't make it to the high-priority list, but can we get true dual-monitor support for Invoke?

While your first thought would be to just stretch the window across the desktop, this doesn't factor in the operation and interface of Invoke. Ideally, with all the real estate that a dual-monitor setup provides, it would be nice to have access to more of the features of Invoke. A wider layout would make it unnecessary to toggle between Layers and Gallery, because the full Canvas+Layers and Viewer+Gallery panes would all fit. This would also make a more fluid workflow for dragging and dropping from Gallery to Control Layers. There should also be much more flexibility available when working with Workflows as well.

These improvements have been on my mind for the better part of a year, but Invoke is finally in a state of refinement that can accommodate these proposed changes. I've attached a couple screenshots showing my desired layout.
