Usability issues - Category titles

I was thinking today actually as I was going through the course listing that it would be helpful to adjust the number of course per page. Of course this is totally possible; however, it is a setting listed under front page settings which does not seem to me to be the most intuitive place for it. I would expect it to be somewhere under courses but the argument could be made that you really only browse courses from the front page. Everywhere else you are in a particular course. In any case, this might be a neat area to explore using AJAX.

==For me the larger question is how does Moodle handle long lists. There should be an option for # of entries per page, ways of sorting and filtering, etc. A comparison of the various long lists (courses, students, participants, questions, etc.) would be good to have. Do each of them function is a similar way? If not, what are the difference and are they justified?
