Of course it'd be optional, but having family trees/ organizational charts with the ability to be displayed on the sidebar of individual forums or even the main layout would be awesome!
They could be used for:
- Models for cars, planes, trains (first model to current model, and sibling models)
- Organizational Charts
- User Group Hierarchy
- Trophy Hierarchy
- Site Maps
- Simple Location Maps
- Road Maps
- Ratings (example: coffee flavor. strongest to lightest, hovering over allows people to see which flavors rank where on the tree)
This could also make a really nice addon, if others agree! Thanks for checking out my idea.
