Would be nice to make components in any image program and import the component to Powder Toy. Of course you'd need to use strict colours but you'd be able to load up stuff people have made just by saving the screencap.
I guess it would be a good idea, but still quite hard to code and time consuming. There are wayyyy more things in the game that could be added to before this. Still a good idea though.
That would be a lot of coding. Color Identifying, and then converting to a stamp file. Then the actual working of some walls. It's complicated to code, but it can be possible if there was a lot of time.
