Two things in particular:
Firstly, on a post with more than one page, the fact that you have to click into the thread and then click on the page number. Why can't page numbers (last page) be shown by post titles as before on old site?
Lastly, on the text layout, why is there a massive gap of empty space between he last thread at the bottom of the page and the page numbers right at the bottom? Can this empty space be filled with posts?
Feel free to add your own...
