Currently shapes are only supported and created by scribbled pen input. Sometimes I want to modify the size in height or weight, rotate or color the shape. It would be necessary to offer modifiable shapes like you can do e.g. in Miro or Adobe Illustrator. Set starting point, move the Apple Pencil to desired ending point and voila your rectangle is created. I wished you could also color shapes with border and background color. I think it would help a lot in daily routines.
