A KiCad Plugin for Drawing PCB Tracks in Spiral Shape
(Sorry, but I'm not the most creative fellow when it comes to names...)
See here for where to put the top directory:
https://dev-docs.kicad.org/en/python/pcbnew/
Besides adding tracks in a spiral shape according to the parameters given in the pop-up menu, which are basically self-explanatory, it adds the tracks to a group, such that the whole spiral can be selected. You can also give the spiral some name, and select its netname and layer. However, keep in mind that KiCad sees this spiral as a track and not a footprint, therefore be careful when connecting the ends of the spiral; the ratsnest won't help you.
(None of which were integrated into the KiCAD GUI, which was my primary motivation.)
The KiCAD team is also already up to it: https://gitlab.com/kicad/code/kicad-footprint-wizards/-/issues/6
I wanted to create spiral or rather Tesla coils on PCBs. Tesla has written in his patents, such as

https://patentimages.storage.googleapis.com/62/90/92/45a5932052a940/US645576.pdf
on these and how they have different properties from ordinary coils. Recent researchers, such as Dr. Meyl have had success in replicating Tesla's findings. This plugin makes it possible for anybody to easily create the required spiral coils on PCB and so helps in replicating "old" technology.
Furthermore these coils may be used for inductive charging of e.g. smartphones / tablets.
