Thank you! ❤️ <a target="_blank" rel="ugc" href="https://github.com/3R3BOS/ComfyUI-3R3BOS-Pack">https://github.com/3R3BOS/ComfyUI-3R3BOS-Pack</a>📦 WHAT IS IT?The ComfyUI 3R3BOS Pack is the essential toolkit designed to bring professional control and visualization to your workflows.Created to simplify complex interactions, this suite focuses on two main goals: "Human-in-the-Loop" efficiency and zero-latency visualization. It currently includes two core tools that will change how you interact with ComfyUI.<hr /><h2 id="tool-1:-prompt-selector-your-prompt-brain">🧠 TOOL 1: PROMPT SELECTOR — Your Prompt Brain</h2>Stop using Notepad. Stop losing LoRA trigger words.This node turns ComfyUI into a fully interactive prompt database.<a target="_blank" rel="ugc" href="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/084ecb9a-0b5c-4108-b02d-08ad466cb6fc/transcode=true,original=true,quality=90/Prompt%20Selector.webm">DEMO</a>Key Features:<ul><li>Built-in editor (create / rename / delete categories)</li><li>Store prompts, styles, LoRA trigger words</li><li>Color-coded system (NSFW, styles, etc.)</li><li>Real-time prompt preview</li><li>✏️ Live override without breaking your database</li></ul><h3 id="important-data-safety">⚠️ IMPORTANT — DATA SAFETY</h3>Your prompts are stored locally in:<pre><code>ComfyUI/custom_nodes/ComfyUI-3R3BOS-Pack/prompts_db.json</code></pre>👉 Always backup this file before:<ul><li>Updating the pack</li><li>Reinstalling ComfyUI</li><li>Pulling new versions from GitHub</li></ul>❗ Losing this file = losing your entire prompt library.Result: faster prompting, cleaner workflows, zero chaos.<hr /><h2 id="tool-2:-batch-selector-(control)">🛑 TOOL 2: BATCH SELECTOR (CONTROL)</h2>Filter your generations like a Pro! The Batch Selector replaces the need for complex preview-and-cancel workflows.<a target="_blank" rel="ugc" href="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/24db21cd-5d5d-411b-a2f9-3ea77277c8db/transcode=true,original=true,quality=90/117741181.webm">DEMO</a>• Visual Selection: Pauses execution and lets you pick the best images from a batch.• Native UI: Draws directly on the node canvas (no ugly popups) with a smart responsive grid.• Resource Saving: Only passes the selected images to expensive Upscalers or Refiners.• Instant Cancel: A dedicated button to stop the workflow immediately if the batch is bad.Perfect for maximizing your hit-rate and saving GPU time.<hr /><h2 id="tool-3:-image-comparer-slider-(visualization)">⚡ TOOL 3: IMAGE COMPARER SLIDER (VISUALIZATION)</h2>The ultimate A/B testing tool for your images. Compare Checkpoints, LoRAs, or "Before/After" Upscaling results with zero latency.<a target="_blank" rel="ugc" href="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/8dc4e7d2-08ad-4ca3-a38c-08c7048330ae/transcode=true,original=true,quality=90/117744816.webm">DEMO</a>• Dynamic Inputs: Connect up to 20 images; the node creates slots automatically.• Zero-Lag Scrubbing: 60fps performance using client-side caching.• Auto-Compaction: Smart inputs reorganize themselves to keep your graph clean.<hr /><h2 id="tool-4:-aspect-ratio-master-(ultimate)">🎯 TOOL 4: ASPECT RATIO MASTER (ULTIMATE)</h2>The definitive resolution calculator. Stop guessing resolutions for modern models like Flux, Wan, or LTX.<a target="_blank" rel="ugc" href="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/e4bbcb99-5738-4aff-b125-68f9b7c19fb0/transcode=true,original=true,quality=90/Aspect%20Ratio%20Master%20Demo.webm">DEMO</a>• Smart Database (2026): Native support for Hunyuan 2.1 (2K), Wan 2.2, Flux.2, LTX Video, Etc.• Magic Numbers: Automatically calculates exact pixel dimensions for VAE requirements (Mod16, Mod32, Mod64).• Visual Grid: Beautiful real-time preview of your aspect ratio and resolution directly on the node.• Labs Mode 🧪: Unlocks community "Sweet Spot" resolutions for maximum quality (e.g., 1.5MP for Flux).<hr />📥 INSTALLATIONOption A: ComfyUI Manager (Recommended)1.
