I'm just learning CF2.5, and I'm working on a little D&D character health tracker app to get my bearings.
Right now I have a sub-app that I load an instance of for each character. I thought I'd throw a button on top of each to close it, but I can't get the button to appear? I'm assuming it's behind the sub-app, but I've specifically placed it a layer above.
Can you just not place things on top of sub-apps? Is there a better way of doing this than using sub-apps?
