Nothing. I have been doing it for a decade. However, for those who are in large categories and are junior--or just prefer to look at the myriad individual rotations out there--I believe that EasyBid (which I don't use) has a superior sorting interface.

Further, though the logic is not changing at all, the new WebApp takes some getting used to. It is fairly clunky, and not nearly as intuitive and easy-to-digest as the existing website. That said there are also some new features that I like, and of course, if enough pilots provide some good feedback improvements will be made.

I just got a DALPA email advertising some webinars, hosted by the PBS and Scheduling committees, further explaining the new interface. I hope to view one.
