I'm currently working on a new launcher for S1 that will be like the launcher for S2 and I'll try and complete it by May. It will be a big update and you won't need QuickTime anymore nor will you have to manually navigate to the SteamApps folder to access the learning resources. All of the videos will be even further compressed without any noticeable loss in visual quality. I'll also be including a project folder for Unity 4.3.4.
