I love the details in the search function you reach through the forums. I feel that if a "for stud" and a "for sale" option were added, it would be much more useful than the current for sale listings. (Through this search it is possible to sort by breed, level, and gene- things that I feel the 'for sale' sort should have.) 

I would also love to see an additional search function within the forums, to find topics. For example, I do not have a surefire way of making sure I am the first person making these suggestions, unless I go through 10+ pages of previous threads.
