Shuffle Lab

Timed, randomized fullscreen image slideshows for drawing practice, presentations, and more.

What's new in 1.0.4

New features

• Break system — configurable break frequency, duration presets, custom break duration, fullscreen break overlay with countdown
• Infinite time mode — manual-only navigation, no auto-advance, JSON-safe persistence
• Settings UI groups with dividers for cleaner layout
• Break timer warning color when session will expire mid-break
• Disable breaks when Infinite duration is selected, with descriptive warning
• Timer display uses adaptive format (s / m:s / h:m:s)

Bug fixes

• Custom duration inputs now capped at 9999s with digits-only validation
• End-of-deck screen waits for user input instead of auto-advancing
• Session description text updated to reflect breaks in total time calculation

Features

• Fullscreen slideshow with randomized images from any vault folder
• Configurable duration per image with presets (30s, 60s, 2min, 5min, custom, infinite)
• Loop toggle — choose whether to repeat images or stop when they run out
• Session timer with real-time display
• Break system — configurable break frequency and duration between images
• Intro prompt slide (optional markdown file per folder)
• Session logging to prioritize unseen images next session
• Language support (desktop only)

1. Navigate to your vault's .obsidian/plugins/shuffle-lab/lang/ folder.
2. Copy en.json, rename it to your language code (e.g. de.json).
3. Translate all values (the text after the colons). Keep keys, {0} placeholders, and \n unchanged.
