I have not spent much time on it either, but the loss of transparent PNGs is a bad thing. IMO
I'd like that too, but it's not as simple as you'd think. Transparency (and translucency) are handled internally by the designer engine itself in such a way that it will work with all image formats that the software can load. This ensures that the editor works the same way for all image types.

I'm looking around and can't seem to find how to make an LED button?
Look in the help under the topic Screen Components. LEDS, DROS, Panels, Labels etc. are all screen components. The topics in that section of the manual explain how to add components to your screens.
