Multistate Change Shape / Image
Be able to change a symbol shape and color. For example, green circles, orange triangles, red squares. This will help colorblind users.
Useful for asset health trafic lights. Using 0,3,4 or more angles in a polygon, or even better to have a list of symbols including polygons and '!', '?', 'X' and other useful symbols for various states for the equipment.
I am currently implementing this by adding multiple multi-state symbols on top of each other, and making them transparent for all other states than the one they are supposed to symbolize. Cumbersome!
