why is there no support for the Amiga's IFF ?

Hey there. Yes, I am open to feedback, so please feel free. I am new to Aseprite and Aseprite scripting, heck this is also my first Lua creation ever as well, so I’m sure there is room for improvement here and there.

Please do so in reply to my post in the Scripts & Extensions forum, though, which I suppose would be more appropriate than here.
