Drawing function for straight lines and shapes

As a user, I would like to be able to automatically create straight lines and geometric shapes (e.g. circles, rectangles) in the sketch function or when editing images in order to be able to display measurements and markings more precisely and professionally.

Especially when documenting in plan or with photos, it is important that not only freehand sketches but also clean, straight elements are possible - ideally with support for Apple Pencil or other pen input. This would improve accuracy and make docu tools much more attractive for tasks such as digital measurements.
