Could there be a nice way to reference an “image variable” in a command, as if it were an image in the stack?
For example, this is something I don’t think is currently possible:
sp +mirror x
store. my_img_var
add[0] $my_img_var
Yes, obviously you can restore the image first with i $my_img_var and store after. But what I’m thinking about is storing non-image data structures in a way which can easily be passed to other commands which know about it. I suppose the general principle is expanding the use of images as variables, outside of the image stack.
Edit: perhaps multiple image stacks is out of the question too?
