"Saving Views" - two possibilities there.
Screenshots - The "Capture Screenshot" option from the Main Menu "Social Menu" (or whatever it is called - the 2nd last icon). This still works in S20.
Bookmarks - This is problematic. N3V claims that the bookmark keyboard shortcuts work in S20 but all my attempts to use them have failed. I submitted a bug report and this did get a response that an "issue" had been found. In the meanwhile I drop back into Surveyor Classic to use bookmarks.
Hope this helps.
