Can you add other shapes to define or point at a specific area?

I was wondering if, besides rectangle and polygon, one could add other shapes, i.e. an arrow or arrowhead to mark an area for annotation. Any advice would be appreciated. Thanks

Dear @AndrasSCH,

the short (but not so good) answer is: no, unfortunately. But it's definitely on my wishlist. (In terms of internal "mechanics", such an annotation would be handled as a point-shape annotation, with a custom marker symbol attached to the point.) I'm sure this will become available at some point. But there are some challenges to be solved first. (I'll reply with a longer & some more context via e-mail.)
