First, I'd like to say that Construct is great, and I hope the word continues to spread because I heard about it at random just a while ago, and it's exactly the kind of thing that I like.
Right now I'm designing a platformer, and would like to use invisible TiledBG objects for collisions and sprite objects on top of them for display. However, I want to resize a TiledBG that is behind a couple of sprites. The problem is, I can't click on it; clicking where I can see it in the layout editor just selects the overlapping sprite objects, since it's within the sprite's bounding box. I could move the sprite object, then resize the TiledBG, then move it back, but that'd be mighty inconvenient; especially since I need the TIledBG to be resized to be as long as the sprite objects I've got laid out right now.
So, my question is, how do I select something in the layout editor that's behind something else? If it helps, it's also on a separate Layer.
