Jupyter Enhancements for VS Code

Supercharge your Jupyter Notebook experience in VS Code with advanced visual cues, smart execution controls, and a dedicated scratchpad.

Jupyter Enhancements fixes the lack of visual feedback in standard notebooks by adding clear success/failure backgrounds, running animations, and better focus management.

🚀 Key Features

1. Visual Execution Feedback

Never wonder "Did that cell run?" again.

• Running Animation: A Blue border flashes around the cell while code is executing.
• Success Flash: A subtle animation flashes upon completion.
• Persistent Status:
  • ✅ Green Background: Cell executed successfully.
  • ❌ Red Background: Cell failed.
  • (Colors are fully configurable in settings)

2. Smart "Run" Controls

We've upgraded the standard execution flow to be smoother:

• Run Current & Below: Runs the current cell and all subsequent cells, stopping immediately if an error occurs.
• Run Single: Automatically advances focus to the next cell after execution.
• Smart Focus: Ensures the editor always scrolls to the cell currently being executed during batch runs.

3. 📝 The Scratchpad

Test code snippets without messing up your notebook structure.

• Highlight any code in your notebook.
• Press F11 (Default).
• The extension creates a temporary scratchpad cell below, runs your snippet, and marks it with a dashed border.
• Perfect for checking variable shapes, quick prints, or debugging logic.

4. Layout & UI Tweaks

Toggle "Compact Mode" to maximize screen real estate.

• Compact View: Toggles line numbers, verbose timing, smaller output font, and consolidated buttons.
• Hide Toolbar: Option to hide the floating cell toolbar for a cleaner look.
