I find it frustrating when my piece ends up in the wrong place because I dragged it and my finger lifted up because of my fingernail. Be nice to be able to confirm moves sometimes. Or maybe I just need a manicure, hah
I find the “show legal moves” button is nice in preventing a mis-click or accidental drag. I enjoy that it lets you select the piece and then select the destination without having to drag. Or invest in some form of Apple Pencil/Tablet pencil variant.
