Click on the create tabs to change stuff. % means to insert a parameter there. (name) % after a string means to turn that into a parameter The Hex colour block only works using hex colour codes.
Everything here was made by me except for the stamp font which I yoinked from @-Rex- monospace font. The blocks are made using the pen tool however the font is not. Right now this is just a demo and you can't do much. This might go somewhere, might not, we'll see. Pls Enjoy :))
