Side by Side Documents in Split View

One of the elements that I love about Scrivener that I wish Sudowrite could incorporate is the ability to have split screens open so I can write/edit things in one document, while simultaneously looking at a second document next to it so I can refer to it while writing my stuff in the first document. I hate having to scroll back and forth across Scrivener whenever I need to refer to something in a worldbuilding card/character card when doing brainstorming in an unrelated document, working on the outline, writing my chapter, etc.

If I could have side by side split screens so I could avoid doing this, it would make things so much easier for me!
