To quickly build a canvas network based on existing links.
It would be cool to be able to select a note element in the canvas and toggle on a Local Graph-like mode. This would temporarily show all immediate connections and possibly have a depth slider, etc. While in this mode, you could permanently add the displayed local links to the canvas by perhaps Control/Command clicking the dotted/grayed connecting line. Once the mode is toggled off, the local connections disappear except those that have been initialized.
