Add another dimension to Andy Matuschak mode?

Thanks, that’s not exactly what I had in mind, but I didn’t phrase that very well. I know you can split the notes like that, but I usually have so much text in my notes that I need them to be pretty big so I can still read all the text and work with it.
So what I’m looking/hoping for is something that looks more like this:

You’d hit a hotkey and then have this overview of all the notes that you currently have open. In a perfect world it’d work like Andy Matuschak mode where you can scroll back and forth between them, because that way I can have all the notes open at once (though you can’t see them all at the same time) and then just go back and forth easily.
