Description

Transform your Anki Deck Browser into a comprehensive heads-up display. This add-on provides immediate visual feedback on your study performance, review speed trends, and upcoming workload without requiring you to open a separate statistics window.

Key Features

1. Advanced Trend Graphs (Speed vs. Retention) Visualize your performance over time with smooth, high-performance graphs directly on the main screen.

Dual-Axis Plotting: Monitor your Answer Speed (seconds per card) and Retention Rate (%) simultaneously to see how speed affects your accuracy.
New Card Glow: A dynamic background glow intensifies based on the density of new cards you are learning, providing immediate visual context to your speed dips.
Smart Smoothing: The graph uses cubic bezier curves and configurable moving averages to turn noisy review data into clear, readable trends.
Auto-Scaling: Automatically switches the X-Axis between Hours (for daily views) and Dates (for weekly/monthly views).

2. Learning Forecast Graph Designed specifically for users with longer learning steps (e.g., 20m, 60m, or 90m).

Standard Anki limits visibility on intraday learning cards. This feature adds a bar chart showing exactly how many cards will become due in the near future.
This allows you to pace your session and avoid closing Anki right before a "wave" of learning cards becomes due.

3. Enhanced Statistics Dashboard

New Card Counter: Track exactly how many new cards you have introduced Today, this Week, and this Month.
Time Remaining & ETA: Real-time estimates of when you will finish your current due counts based on your rolling mean/median speed.
Median Speed: Displays a robust speed metric that filters out outliers (like leaving a card open while taking a break).

4. Configuration

Tools > Speed vs Retention

Customization Options:

Layout: Move graphs to the Top, Bottom, Left, or Right of the statistics text.
Visuals: Full control over line thickness, dot radius, graph height/width, and colors (with Night Mode support).
Data Source: Toggle between viewing data for Today, the Last 7 Days, Last Month, or All Time.
Filtering: Option to restrict statistics to specific Decks or Tags.

Compatibility Works with Anki 2.1.50 and newer.
