[QGIS-Developer] Best practices for storing plugin settings

[Johannes Kröger (WhereGroup)]

Hi Gabriel,

there are no fixed standards but it might be a great project to evaluate 
the plugin landscape and see how people do it in the wild, to see if 
there are some defacto standards or best practises.

I tried to document some variations I found recently in 
https://hannes.enjoys.it/blog/2023/07/plugins-in-qgis3-ini/

There should also be a post to a QGIS mailing list where I asked about 
standards but I cannot find it again because mailing lists. Iirc the 
answer was "there are no rules".

Cheers, Hannes
