I'm very sad when looking at all these mind managers.

They are all some sort of simple tree outliners, with the root item placed in the middle (and the children around it), or on the left, or on the right ... grrrrrrrr

The only one (that I know of) that goes a step further is The Brain, which provides several useful views, the classic one is where you can see all the item's parents, related items, and linked items, or the expanded where the close items are expanded ...
