I'm working on this along with staircasing in my own [repository](https://github.com/ua-kxie/circe/blob/3f6b8c1c2c8d8d1095069362c138275f4f4281a6/src/schematic/circuit/pathfinding/mod.rs) It is working for staircasing, I have yet to test it for reusing the results from previous pathfinding

gotcha. Thanks for the prompt response! unfortunately, I don't think I can implement either of these :(
