There are posts-per-page settings (I use 100), but there are no settings for threads-per-page.

Me, and probably some other people, need more threads on each page.

Why click on the little 2-3-4-5 page numbers just to see recent stuff...

Want more recent threads on a single page? Not the best solution, but you might want to take a look at the Archive (.) (latter pages have the most-recently created threads).

EDIT:

Or, you can look at the the Thread Display Options near the bottom of the page and pick Sort Threads by -> Thread Start Time, that way you get the latest 30 threads created within that forum (because, in case you didn't know, 30 threads are currently being displayed on each page, Sticky threads not included in the count).

I see 30 threads per page, what the hell are you seeing? 30 is plenty imo
