Split Screen (pages)
Workspace for designing the screens.
Viewer mode (a second "page" of screens).
Screens are split like an Excel "freeze' screen.
Working on mobile app
Reviewing UI material in page based layout, not Symbols!

Make it possible to split a screen to compare two boards. Also to show two files next to each other.
And a matching topic overall would be Tabs for multiple open files:

I'm not working on a particularly large document (I'd imagine there are UI projects far bigger than mine) and I have run into this very issue. I feel split screen is the obvious way to handle this but that could be just as clumbsy to navigate... it's more like "bring me back to the last screen I was just working on. Maybe something of a keyboard shortcut that takes the user back to the screen they last used?
With large projects it becomes hard to keep oversight. Multiple windows with different views of the same document would help copying and pasting. (WHen I find what to copy, I cant find my way back to the place I want to paste it.)

Like powerpoint, I want to open multiple windows on the same XD document. The reason is that I use multiple monitors and I would like to see two different spots in my large document. I cannot share a prototype as I am still in the design process and I am not looking to link items up yet.
