Great news: I finally decided to make eDriven.Gui Free and Open Source!!!
But first, I’d like to thank once more to anyone who helped me financially by buying the package. You guys are great!
Download and install the Unity package here: https://www.assetstore.unity3d.com/en/#!/content/3796
Get the source from GitHub: https://github.com/dkozar/edriven-gui
And yes, I’ll be more than happy to accept your eventual bug fixes (pull requests)!
