zoom to focus on connector's target
This might be stretching Mural's core functionality, but, it would be great if somehow you could navigate through a mural by following connectors. You could work your way through a decision tree by, say, selecting a connector, and the canvas/view would zoom to the next node in the tree.
This would be useful in all sorts of ways. who else would like to have an accessible, interactive flowchart environment? Everyone, that's who. You could present with it, develop with it, debug with it…
It would be most effective, tho, if other issues (like how connectors don't "stick" to links very well) were resolved.
