⚡ Jupyter Enhancements ⚡
Supercharge your VS Code Jupyter Notebooks with visual feedback, smart execution controls, and a power-user toolbar.
🚀 Overview
Jupyter Enhancements transforms the standard Jupyter experience in VS Code. It adds immediate visual cues (flashes, borders, backgrounds) so you know exactly which cell is running, which failed, and which succeeded.
It also introduces a "Power Toolbar" floating over your cells, giving you one-click access to splitting, merging, scratchpads, and clipboard operations that are usually hidden in sub-menus.
✨ Key Features
1. 🎨 Visual Feedback System
Never guess the state of your cells again.
- Running: A distinct Blue Border (customizable thickness and position) appears while code executes.
- Success: A brief Yellow Flash and a persistent Green Border/Background confirms execution.
- Error: A Red Background immediately highlights failed cells.
A floating menu appears on the active cell with essential tools sorted for speed:
- ▶️ Run & Select Next: Execute and immediately move to the next cell.
- ✂️ Split & Merge: Split a cell at the cursor or merge with the one below instantly.
- 🗑️ Clear Output: Instantly wipe the output of the current cell.
- 🧪 Scratchpad: Run the selected text in a new temporary cell (Above or Below) without breaking your flow.
- 👁️ Toggle Output: Collapse/Expand cell output.
- ⬆️⬇️ Move & Copy: Move cells up/down, copy, paste, or duplicate with one click.
3. 🧪 Smart Scratchpad
Need to debug a variable without adding a mess to your notebook?
- Highlight code -> Press
F11 (or use the toolbar).
- It executes in a temporary "Scratchpad" cell with a dashed border.
- Perfect for quick data inspection.
- Compact View: Optional tight layout with verbose timing and line numbers.
- Optimized Startup: Skips unnecessary terminal activation steps for faster kernel loading on Windows/Conda.
