Introduce a return function in Bluebeam!
For example; Let's say there are annotations on the floor plan that have hyperlinks that take you to that annotated elevation and from there you click another annotation marker on the elevations that takes you to that detail and if you want to go back, you either have to remember the page number you were on or you have to physically scroll to that page and find that floor plan again. If there was an easily accessible return button, we click it and it takes us back where we started exploring (the floor plan).
