• Command Palette & Dark Mode: A modern TUI experience with a built-in command palette (Ctrl+P) and dark mode support (Ctrl+D).

Understanding the Interface

1. Live Monitor Tab

This is the default view. It shows:

• Summary Cards: Total Upload, Download, and Combined Usage for the current session + history.

• Quota Bar: If a limit was set, this bar fills up. It turns Yellow at 80% and Red at 100%.

• Live Table: A scrolling list of network speeds recorded every second.

2. History Tab (24h)

This tab visualizes your traffic over the last 24 hours.

• Rows: Each row represents a 1-hour block of time (e.g., 14:00 covers 2:00 PM to 2:59 PM).

• The Bar:

  • Solid Block (█): Represents Download traffic.

  • Shaded Block (░): Represents Upload traffic.

• Total: The text on the right shows the exact data transferred during that hour.

Tip: If the graph looks outdated, press r to pull the latest stats from the database.
