🎯 The Problem We Solve

As developers, we constantly work with terminal commands, but:

• 🤔 Forgetting complex commands with multiple flags and arguments
• 📝 Searching through terminal history for that one command you used weeks ago
• 🔄 Retyping the same commands across different projects
• 📚 Maintaining scattered notes of useful CLI snippets
• ⏱️ Wasting time searching StackOverflow for syntax you've used before

VAUL solves all of these problems by providing a beautiful, instant-access command vault right in your system tray.

💡 Usage Examples

Basic Command Management

Saving a Command

1. Type your command in the input field: docker-compose up -d
2. (Optional) Add an alias: start-dev
3. Select a category or leave uncategorized
4. Press Enter to save

Using Commands

1. GUI: Click the tray icon → Click command to copy → Paste in terminal
2. CLI: Type vaul start-dev in terminal to execute directly

Advanced Features

Category Organization

# Create categories for different types of commands
- 🐳 Docker Commands (Blue)
- 🚀 Deployment Scripts (Green)
- 🔧 Git Workflows (Orange)
- 📦 Package Management (Purple)

Alias Examples

# Instead of typing this every time:
docker-compose -f docker-compose.prod.yml up -d --build --remove-orphans
 
# Create an alias: prod-up
# Then just run: vaul prod-up

Fuzzy Search

# Type partial command to find it:
"docker" → finds all docker commands
"deploy prod" → finds production deployment commands
"git reb" → finds "git rebase -i HEAD~3"
