I've been working on a fork of a html presentation framework, (flowtime.js), intending to extend it from a nxm 2D grid, to a 3D outline, much like Leo. Well if its going to mimic Leo, why not borrow some of the design?
Well, when I hit the doc's, I found that all of the tnode, vnode, parent/child, DAG stuff seems to have been deleted from the documentation, perhaps it is meant to be moved over to the "everything developers need to know" manual?
I got a hard copy of an older version around here somewhere, guess I go hunt it up.
