For Level Master 2000, this means:
- Support groups in entity explorer
- Project management (new, save, load)
- Undo/Redo create and deleting entities/components (video to come)
All implemented. For my thesis this means: written a first version of chapter 3: overview of rapid prototyping tools. As posted recently, it’s in German, but I’ll port it over to English as soon as possible!
