Features

• Cross-Platform: Now it's available on Windows Linux and macOS.

• Modern UI: Comes with a much cleaner, user-friendly interface and a built-in Night Mode.

• Multi-Selection & Editing: Select multiple charts or nodes to move, delete, mirror or copy-paste them easily.

• Built-in Helper: Includes an overlay with all keybindings

• Improved Save System:

  • Saves the full pattern regardless of your viewing or zoom position.
  • Generates a PNG image containing pattern metadata, which can also be used for loading patterns back into the app.
  • ⚠️️ ATTENTION! Do not send the PNG file via messaging apps (e.g. Messenger, WhatsApp, etc.), as they compress images in a lossy way and corrupt the saved pattern data. Always send the .json file or compress the PNG into a .zip archive.

• Interactive Row Tracker: Darkens every row except the active one to help align your eyes while weaving.
