Is there any way to change the size of shape handles? Also, is there any way to change the color of handles to green (as in Visio 2013) for all shapes and lines that are selected? The huge globe sizing of the handles gray scale is very annoying.
No, not as far as I'm aware. Size and color of these adorner elements are fixed I'm afraid. There's some ability to change colors in the registry (if you have this turned on in options), but it doesn't include shape handles.
Best regards
