Often I have symbols that overlap. Take this circle and this mail envelope as an example:
That’s two separate objects. I’m aware of (And very grateful for!) the feature where I can right click over the both of them, and will be allowed to select from the pop-up menu which object I want to select.
If I select the envelope in this way, I get the following:
It’s a little hard to tell but there is now a selection box around the envelope symbol.
However, if I hover my mouse over this selected object and click to drag so I can move it, instead I start moving the circle.
I suspect this is because the circle symbol is actually in a layer above the envelope, but in this case I have intentionally selected the envelope. The only way I can move it is with the keyboard (The arrow keys), which is not ideal.
I feel that if the user has gone to the effort to select an object underneath another object (Something they can hardly do by accident!), then that selection should take precedence over layering if the user then drags to move.
