The only difference I see between Basic 19 and Basic 20 is that Basic 20 adds the "Reset Current View" option. That resets the view if you've rearranged columns or removed columns via drag and drop.

Professional did change..

"Column Headings" became "Add/Edit Custom Views" & "Reset Current View".  Note the screenshot below is for the December Release.. we added a way to export/import Tax Year 20 Views between machines. We also added a way to import exported TY19 Views via the Add/Edit Custom Views wizard.

I put up a youtube video to explain (specific to December release). Be kind, i'm an engineer not a polished voice actor.
