1. I created a nice [documentation about managing states](https://castle-engine.io/states). Some of this information was already available, but scattered over the manual and not so clearly organized. The new page should serve as a clear documentation how states are supposed to be used.

2. We have a nice [list of TCastleTransform descendants](https://castle-engine.io/viewport_and_scenes) with screenshots in the manual page about the viewport. This should serve as nice description “what I can put in a viewport”.
