peopleinside that's right, I didn't test with pinned discussions or search. This reminds me pinned should be added to the mass actions as well!
I had to hard-code the color for each of the discussion list item elements, so I'm not surprised it needs more code for the excerpt. I'll try to take a look.
The styling is very likely to break even more because it's using the primary color as background, so white might not always be the best text color.
I have also not tested dark mode at all. It's probably horrible. That's for a future update 😇
