1. simplified X11 floating WM, clone of my current frameless XFWM window theme
   • First steps: rectangle (titlebar) above window contents that can drag the window, close button within the window contents
2. simple 3D mesh editor+part/face colors (VC), 2D workflow with extrude/revolve, project palette management
   • First steps: hexy triangle mesh with faces that can be painted+deleted, manually place faces (think wooden pattern blocks), any depth (vase, multiple heights, multiple sides/parts, transform)
   • the sort of thing you could make wall decorations, mesh particles, chess pieces etc
3. gridmap editor supporting multiple sizes, semi-modular room creation
   • First steps: cuboid cell placement+space reservation, single-layer auto-tile (made of at least 3 cell types, though I also have an outer corner for hallway junctions)

This assumes I can figure out how to do these at high-level (using libraries, not writing mesh stuff completely from scratch).

EDIT, an extra:

4. At one point, I wanted to make something to take analog input from a gamepad trigger and turn it into pen pressure (in one hand, position from mouse in other hand). Some people have looked into this for sc-controller but it didn't seem viable (input type mixing might be an issue). I wonder how much just an evdev rule or two could do.
