I like it, but I still find the line of text underneath the title distracting. It makes it harder for me to parse the list of topics titles.
I get that you didn’t like removing them completely as I’d suggested earlier, but that said, we don’t even have the created time in the list today… do you really find that problematic?
Also, the categories were easier for me to scan when they were in their own column, though I do like the de-emphasized colors.
