A note on cross-links: Cross-links (the yellow boxes) are a vital part of DebateGraph. They allow you to jump "sideways" through the map and across maps. It can be a bit disconcerting at first, but they are a valuable tool in making connections and building on work already completed. Thanks.
In the Graph views (Explorer, Bubble and Dagre) cross-links are indicated by a dotted line as well as the reference color yellow.
