Updates to this screen should make changing models and textures much easier and you'll also have the option to upload new models and textures to the server thru the client.
In addition to model and texture uploads, there are also new options on the world editor menus giving world owners & sysops the ability to upload and refresh the landscape heightmap, news.txt, welcome image, buildings.dat file and everything else you'd normally need to have direct access to the server folder to do.
