Save custom layouts

[kylebutts]

It would be a nice feature to create custom layouts similar to "Stacked", "Side-by-Side", and "Notebook". On my big monitor, I prefer a different layout than when working on my laptop. I could imagine the interface being "save layout" and "load layout" or something like this

I think this sounds pretty much like #7599. Do you want to take a look to see if you agree and add any additional info on what you are looking for?
