Locked boxes remain selectable and reject movement, resize, numeric edits and deletion. Saved with workflows; Undo/Redo supported.</li><li>Connect Load Image IMAGE to Canvas reference_image for a reference underlay without running generation. Default OFF, opacity 50%; loading or toggling display keeps Canvas dimensions unchanged.</li><li>Match image size sits beside the display toggle. It explicitly fits dimensions to a multiple of 16 and scales boxes, with Undo/Redo. The reference is a layout aid and does not condition generation.</li><li>Japanese/English help and README include wiring instructions and the supplied usage screenshot.</li></ul>v1.0.4Added Japanese/English tooltips, fixed Preview disappearing when zooming out, and stabilized the coordinate controls. Updated Standard and DMD workflows now include a connected BBOX Preview.Download both workflows from the GitHub Release. Classic ComfyUI UI is supported—no Nodes 2.0 or separate Krea2 installation required!V1.0.0includes the Canvas editing improvements introduced in v0.1.4:<ul><li>Undo / Redo: restore drawing, moving, resizing, deleting and resetting BBOX layouts, with up to 60 edits per Canvas during the current editing session.</li><li>Keyboard shortcuts: Ctrl/Cmd+Z to undo; Ctrl+Y or Ctrl/Cmd+Shift+Z to redo while the Canvas or its history buttons have focus.</li><li>Overlapping BBOX selection: Alt+click to cycle through overlapping boxes. The selected box has a white outline and can then be dragged normally.</li><li>Canvas shortcuts avoid accidentally triggering ComfyUI’s workflow-level Undo.</li></ul><h2 id="installation">Installation</h2>Open a terminal in your ComfyUI folder:<pre><code>cd custom_nodes
