Deleting single note takes multiple clicks in agenda. Deleting multiple notes are pretty lengthy process. I feel there should be single click or gesture option to delete multiple notes at the same time. The same way moving multiple notes to different list should also be easily accessible. I understand there is an option to drag and drop but It’s not that easy to use on iPhone.
On iPhone it’s indeed not very easy to delete multiple notes, but we’d argue it’s also relatively rare you’d do a lot of large reorganisation on the small screen of the phone. On iPad you can start dragging a note and add with your other hand additional notes to the selection, then drag and drop them to another project or the trash if you like.
