Merge this project with undo/redo branching.

Hello, very nice idea.
Please collaborate with https://github.com/paradoxxxzero/atom-undo-tree.
It would be quite powerful and extremely cool to visualize a tiny-ish tree of the typing history, and mix the finger pattern with navigation on the undo/redo branches !
A simple DAG would suffice for a start.

This is a feature not so important in an editor, but maybe hopefully one day it will be integrated in firefox with tab tree views and be so great :)

Merci déjà

Start by reviewing the requested collaboration with atom-undo-tree and the proposed tiny DAG for typing-history visualization. Define the integration scope and how undo/redo branching should interact with finger-pattern navigation; done would require an agreed design and working collaboration path.
