In our use of filters I thought it would be useful to keep the list as short as possible, by nesting related filter names under more general names.
Don't immediately see how to make it happen in Flare.
Is anyone doing that? How?
Meanwhile, the other product documentation teams at my company are doing it with markdown, Pelican, and a plugin - they've abandoned Flare. As a user, it's nice not to have to deal with a long list of filters on docs for a complex product. As a writer, I'm not eager to keep piling-on features that have to be implemented in python post-processing. That way lies madness... or switching to markdown...
