It would be great to have more predefined shapes in the shape list. While most are there, the ability to add and adjust more shapes would be great. For example, I would like to add a trapezoid to my board. But the trapezoid available can only be adjusted in length and width. I would like to be able to alter the angle of the sides as well. Other additions of triangles, lines, arrows, cubes, pentagons, octagons etc would be very useful.
Allowing users to adjust those shapes in other ways then just length and wide could be very useful. I find myself moving over to powerpoint to create visuals that I have to then move over to Miro to share with my team.
