Make the canvas readable at a glance. LinkModeToggle adds: Hotkeys: F8 or Ctrl+K to cycle Spline → Linear → Straight Toolbar button: a small bottom-right canvas button (next to Fit/Zoom/Minimap) with a mini badge showing the current mode Persistence: remembers your last mode per browser (localStorage) Designed for the modern ComfyUI frontend (v1.31+), but falls back gracefully on older LiteGraph builds.
