You can't save textures for now lol turbowarp is a good idea some bugs to correct, like the alpha channel isn't show in the box on the bottom-left. I have to add 'shapes tools' (tri, ellipse, line..), to make the UI better and to do a import export system. (will be compatible with my 3D engine)
thanks to @-rex- for the rectangle filler and the sfe (basically stamped pte) thanks to @awesome-llama for inspiration
