Obsidian plugins with #layers#

The HandLayers plugin adds editable handwriting and drawing layers to Markdown and PDF files without changing source content. Apple Pencil or mouse input creates ink while touch remains available for page navigation. Its tools cover pens, highlighters, text, shapes, lasso selection and temporary whiteboards, with controls for moving, resizing, rotating, recolouring and arranging annotations. Layers can be named, reordered, hidden and given individual opacity, and their JSON data stays inside the local vault. PDF workflows support visible annotation merging and ZIP exports containing source files, saved layer SVGs, JSON and a manifest. It also provides non destructive image processing for PDF regions and Markdown images, including colour selection, cleanup, cropping, rotation and perspective correction.
