A collection of small addons for Blender, mostly documented on my blog
If you are interested in developing add-ons yourself, check out this repo, blenderaddons-ng which is configured to provide easy testing, benchmarking, profiling and automated testing in Vscode & GitHub actions. New add-ons and fixes for existing add-ons will most likely appear in this new repo. The first add-on that was moved is select_colinear_edges.py, which you can now find here.
sometimes the add-ons are updated or tested against the latest version of Blender. Information on this can be found in the file STATUS.md.
Of interest to users of planks.py (the floorboard generator): Karl Andreas Groß has created a wood shader collection that includes settings for use with the add-on. His shaders are available on https://cgcookiemarkets.com/all-products/prowood-procedural-wood-shader-pack/
