It drives me crazy that notes does not reorganize the list when you check things, but that's probably because it's just markdown. My wife also refuses to use it. Carnet is the google keep like alternative that I think would work for me, but the sharing isn't working currently, whenever the note is updated the share is removed.

Never used dockge sorry

I can't remember if I reloaded a previous save or fast traveled out of there, but there is a way to heal down there I believe

Honestly if your going to go through all this effort to make this work, and already have a pi, I would suggest instead upgrade the control board to something with extra fan headers, led heads, etc and switch to klipper, there have to be guides out there for your specific printer

Powering the fan from gpio pins probably isn't going to work out well either, they are 3.3v and 5v. Powering the fan from the PSU is going to be similar to powering a pi off it, I believe you should step the voltage down to what each needs, where the fan is 24v I think the pi is 5v. Your PSU is probably 115 or 220 v. For connectors I would expect to have to redo them yourself with micro fit, molex, jst or w/e you want and can get. On some of mine I just did single pin molex on the pins of the white female connector for fan headers, it doesn't lock but it works if you don't have a lot of movement.
