1) Replays will automatically grab the players rating, league, and more from Battlenet. That enables the replays to be sorted by an Average rating of the two players, along with the league of the players, so that you can be sure you are downloading a replay from quality players (if that is what you are going for)
Note: Still having some trouble grabbing Korean data since their language looks like hieroglyphics to me and my webserver.
2) Now you can download replays directly from the main results page, check it out -- http://www.replayladder.com/site/replays
(also planning to implement direct zip compiling and download from the main results page, so you can use the filters to narrow down things like a favorite player for instance, and then download a bunch of different replay files at once)
3) Player search from main results page.
Plus all of the great features for viewing individual replays still there. View build orders, view details and events of the game etc....
So if you haven't checked it out yet nows the time, more sweet features coming soon!
