Per, I hate to answer this with “try something else”
But I wonder, what is holding you back just terminating usage “suppress uncategorized” on Arduino?
I find this whole feature a confusing curveball, in a parallel universe I would just delete the site setting, topics need a category so having this universe where topics have a category (but don’t really have a category) is confusing and really adds so little to end users given you can just chuck stuff in “general” if people can not categorize.
Would you like us to help with porting the “grab back of topics that are not categorized” into a “General” category?
