Type-ahead in the graph view: start typing while the graph is focused to filter, and draw a highlight ring around nodes whose title matches. Optionally keep every node visible and only ring the matches.
Color graph nodes by hop distance from the active note, as a gradient between two colors.
Pan the graph view by scrolling instead of zooming. Zoom with pinch or Cmd/Ctrl+scroll. Great for trackpad users.
Highlight new or recently edited notes in the graph view, with one-click 'mark all as read'.
