On the configuration screen can you change the OUTPUT box so it maintains the first image and colors it like all the other boxes on this screen.

What it does at the mo is it replaces the first image completely with a full color square.

Example see below

I don't think I'll be doing this, sorry. Too little priority alongside all my other tasks :(

Let me know if this becomes an actual issue, I will reopen and see what I can do about it.
