tldraw is a very good whiteboard for the web. This extension will let you use tldraw inside of VS Code, using offline .tldr files. Create drawings, diagrams, or visual documentation, and then commit the files alongside your code!
To create a new tldraw file, use the provided command: "tldraw: New tldraw File".
To view an existing tldraw file, open a file with the .tldr extension in VS Code.
Tip: The .tldr files you create with this extension can also be opened in the tldraw web app. You can also use this extension to open .tldr files saved from the web app.
