Split right use case

What I’m trying to do

Trying to see a use case for the split right option.

Things I have tried

I’ll give you one:
The same document can be seen in different viewing/editing modes. You can link the pages up and then if you scroll, they are both scrolled.
One one page you can have the dataview query in source mode and on the right the results so you can change something and get different results, etc.

Split down and split right are also good for initiating halving your workspace so you can drag and drop stuff around on the halved areas, in which you can further split down and right until you run out of screen real estate (you can zoom out to 91 or 83, etc. percent to counter this).
