How do I click only whats in the foreground?

Mouse > Object On Click

Super useful, but annoying that I can click on an object and have it activate a click for an object in the background or different layer. I played around with is visible and as long as I make things invisible this works but overall it is a pain in the buttocks.

Is there a way that I can use on click and have it only activate the top most object?

You can use the object's Z Order>Pick top/bottom condition to select the topmost object of a given type.

Sounds like a good work around, thank you
