ArcPro now has graphics layers for a map which you can capture ad hoc graphics into. I especially like the fact you can have many graphic layers. ArcPro also has Map notes which compliment the graphics layers.
In ArcMap you could convert graphics captured on a map into a featureclass. The current version of ArcPro (2.8) appears to not allow you to convert\export graphics out of graphics layer into a featureclass. You can share them into a layer file but not actually convert them into more concrete features in a featureclass.
My idea is to enable the graphics layer to export it's graphics to a featureclass or at least into a Map notes layer. I would envisage this functionality to be an option in the pop-up menu when you right click on a graphics layer in the contents panel
