By the way,

Do we really want to use seemingly arbitrary categories in the list? I am almost sure that those tags will be bloom after the takeoff, and we'll probably get redundant category tags like "GUI", "user-interface", etc.

Wouldn't it be better to aling the categories with upp's main directory structure, ie.a functional categorization, like "Core", "Core/Plugin", "CtrlLib", "Draw", "Examples" (users may want to provide more example code with documentation), "Application", etc.
Package readme, if provided, and short summary that appears on the list, already give the idea as to what the package does.


Best regards,
