The addon is free to download and use for commercial, school and personal projects. It's main purpose is to manage over 1000 models available through Chocofur, so the design and functionality are pretty straightforward. You can of course add your own assets to it and, in near future, create custom user categories. To learn how to use it simply follow this 8 min video tutorial:
I look forward to your feedback and really hope you'll find the Addon useful. If there's anyone who'd like to contribute in developing the missing features feel free contacting me :-)
Best wishes to you all!
