Sorry I don't know where I should post,
if I wrong, delete it, but do not forget it, tell other people know, please.
As a film writer, mind map is very useful,
it can help people parsing the relationship of characters,
parsing the story development clue,
even make work plans in the meeting.
But usually the software of mind map is 2D, like XMind.
the 2D picture is very complex when there are a lot of relationship lines.
If Blender have a 3D mind map editor,
the things will be more immediate, and more interesting.
3D mind map editor, there are many preset of shape, lines, tools, animation, etc.
user can build their 3D mind map very fast, and enjoy in it.
Here is aN example not very mature I done by BGE.

Perhaps...Blender can became an engine for all 3D software in the future,
For example, 3D Office, 3D Word, 3D Excel...Even an 3D operating system.
Let's start it from 3D mind map at first.
Thank you for your see this letter. Sorry again if I post wrong place.
