Feature: Group Topics by Category

When I open a Categories page I'd like to see Topics grouped by subcategory. I edited a screenshot to show what that might look like:

I.E. just put the topics under each subcategory that they belong to. Note that I have the Topic List Thumbnails component installed.

Currently the view options all result in all the categories being listed, then all the topics being listed:

For our use case that takes up too much screen real estate on subcategory headers, I'd prefer to see them interspersed.

Is anyone aware of an existing component or setting that would accomplish this?

Discuss this on our forum.
