i don't see why 10 posts per page is confusing?
(did i misunderstand you there?)
if you find it confusing with so few(or many =>) posts per page, you can change this in the control panel under options; 5/10/20/30/40 posts per page...
the only thing i dont like is how the original poster's name is underneath the thread title, thereby nearly-doubling the amount of space each thread takes up on my screen in the list (halving the number of threads I can see at any one time). There are a lot of things like that, that are currently taking up a lot of unnecessary vertical space on the page and making it look untidy (not to mention less user-friendly).
