Why isn't the Continuity markup available directly in the Preview app?
Seems indirect/annoying to have a screenshot that's open in Preview and to markup with iPad, quit the app, find the file, press space-bar, then mark it up.
It would be best to just make the continuity option available when in the markup menu in Preview.
I love the Continuity feature, it's nice to not have to type all the time and draw instead :)
