6) Arbitrary {format,palette}s ({4,8} bit ANSI/mIRC, etc.)
7) Hotkey & graphical interfaces to {composed,parametrised} tools
8) Layers, layout (e.g. for comics, zines, etc.) & asset management (e.g. kade, lion, etc.) & traits w/ {inserting,merging,linking}
9) Sprites & scripted (Python?) animation on the basis of asset traits and {composable,parametrised} patterns (metric flow, particle system, rigging, ...)

a) geometric primitives (arrow, circle, cloud/speech bubble, curve, heart, hexagon, line, pentagon, polygon, rhombus, triangle, square, star)

a) Settings panel
