📦 The Collection

This pack is designed to grow. Currently, it includes two core tools focused on UX and Efficiency.

---

1. Batch Selector (Control)

"Filter your generations like a Pro." The Batch Selector replaces the need for complex preview-and-cancel workflows. It pauses execution, allowing you to visually select the best candidates from a batch before passing them downstream.

Features

• Native Canvas UI: A responsive, pixel-perfect interface drawn directly in the node graph. No floating HTML windows.
• Intelligent Layout: Automatically adjusts the grid to fit your image aspect ratios (Portrait/Landscape) without distortion.
• Zero-Overhead: Only passes the selected images to the next node (Upscaler, Saver, etc.), saving massive GPU time.
• Workflow Control: Includes a dedicated CANCEL button to instantly stop the workflow if the batch is unsatisfactory.

2. Image Comparer Slider (Visualization)

"The ultimate A/B testing tool." A high-performance slider to compare Checkpoints, LoRAs, or "Before/After" Upscaling results with zero latency.

• Zero-Lag: Client-side caching ensures 60fps scrubbing.
• Auto-Compaction: Smart inputs reorganize themselves if you disconnect a source.
