I'm often in a plan and will click on a link to a detail. Then after panning around and making notes I have to find my way back to the sheet I was on previously. It would be nice to have a button to go back where I left off. Also thinking of when reviewing a paper set of plan - if I wanted to make a quick look between the RCP and the mechanical plan for example, I would just put a hand in each page and flip back and forth. Challenge with Bluebeam is the section I'm zoomed into on one page isn't the same section I want to see on the other. So using the Previous View and Next View buttons don't work that well.
