Continuing the discussion from Limit number of topics from each category on Latest page:
The above is marked “solved”, but it turns out to be a workaround and the actual answer is “nope”. I have the same concern about one category overwhelming the others.
On mobile, the per-category setting “Number of topics shown on the categories page” works just fine (although obviously a little differently, since the topics are separated by categories).
I’m using desktop category page style “Categories and Latest Topics”, and expected (and would like!) that setting to apply to the Latest list.
I gather from the linked post above that the answer is “nope”… but could that be changed? People who want that list to have everything could choose some large number, and the setting would become meaningful for everyone else…
