 because of the possibility of losing that data or it not being kept *with* the
 code, so issues are being tracked *in* the repo - here.
 
+- [ ] Priority: Write documentation for what currently exists and how it is organized.
+
 - [ ] Add a test moon to verify nested orbits work.
 - [ ] Figure out how to integrate player movement with orbits instead of being separate modes of movement.
 - [ ] Figure out a concept of spheres of influence based on body mass.
 - [ ] Make finding a closest object BY sphere of influence so that orbits are a bit better instead of JUST distance. (Basically, it's higher mass reduces "distance" when sorting. Maybe just do `distance - mass` because that's a quick and dirty way to have something working. Except my mass values I think are very large, so maybe `radar_size` or something between is a better scaler. Although I want mass and size not directly related so it SHOULD be based on mass.)

 - [ ] Need to rewrite with very basic generation - 2/3 planets in random orbits that don't conflict.
+
+- [ ] I added libraries with the intent of adding saving/loading, but haven't done anything with them yet.
+
+### Ideas
+- [ ] Instead of only displaying a single most recent message, having an actual console could be useful.
+- [ ] Double check all functions can handle edge cases - mostly by aborting.
+
+### Stages
+1. ✅ A ship that moves.
+2. ✅ Resource points. The player can hold a button to collect those resources and store them on their ship.
+3. ✅ The resources collected by the player can be spent on something, like improving the ship. Speed, capacity, collection speed, etc.
+4. (save/load?)
