The Open in Cursor plugin adds a command and configurable hotkey to open the active file in Cursor IDE and position the caret at the same spot. It works across Windows, macOS, and Linux, making the handoff from note-taking to code editing quick and consistent. You can launch it from the command palette or bind your own shortcut, avoiding context switches and manual scrolling in large files. Settings include a custom path for the Cursor executable (handy when it's not on PATH), notification toggles for success and errors, and a debug mode for troubleshooting.
