Neuron includes a web interface for your notes that update automatically. This very site you are viewing is managed by neuron; and you may access its notes here. The “zettel” you are viewing currently is conceptually termed an “overview zettel”, as it provides a portal into the other zettels.
Neuron also generates a complete index (at z-index) of all Zettels visualized as a category tree.
The “connections” panel below provides the outgoing or incoming links to/from other zettels.
