Having multiple floorplans open at once, so it's easier to flick through plans rather than going up and down in stories.
Eg, whilst working on a module on a different story, I want to be able to quickly go to another floor to check how it updates. Especially when it's a dense file and it takes a while to reload. Hence having two plans up at the same time (similar to having the section/elevation up with the floorplan).
