I’m eager to test this component here in 
for we have so many groups and categories, and it may be useful to mix and match and reduce the information overload for occasional participants. This requires a bit of thought, and maybe to make some test drives somewhere™. @natacha, @Nemael, would you like to think about it within a month or three?
