I can’t get @lubos’s solution to work with the current Discourse version. The reason is that pinned topics has:
- no category column,
- a first column with
colspan=2.
So when hiding td.category, the resulting table has pinned topic’s rows larger than other rows.
I’ve tried to hide the second column with td:nth-child(2), but it has the drawback of hiding pinned topic’s authors (plus maybe it’ll break on mobile).
Since 2014, has another solution to disable categories on small forums been implemented or figured out?
