Inspired by Utz, I ported the old Briggs lab tools to ChimeraX in a single bundle named Geopickr, with some extra utilities (geopicking on morphometrics surfaces!). I've submitted it to the toolshed, but in the meantime: github.com/baradlab/Geo...
Claude Code is pretty good at writing ChimeraX plugins! This one is almost entirely good context and some prompting: github.com/uermel/chime... Most likely older plugins could be ported over that way relatively easily.
