Can a fancy design be a mask, so you can't click on it.
Then I can use it as an edge.
If you add a image en later the design, than you can't click on te image.
Sorry, I do not quite understand what it is you are trying to do?
Sorry, you can not make the design a mask, however you should be able to simply make it not always be on top (deactivate the stay on top option)
