Was hoping that Pro would allow you to snap your layout graphics to the map data in the layout frame but alas still have to convert them to map
graphics...even worse, the snapping menu is visible on the layout screen bottom but does not work in layout...just to tease you..or am I missing something?
One improvement though, the full line, poly and symbol arcmap graphics are now available for layout graphics on the fly rather than having
to set and reset defaults or select and change symbology after placement.
