📦 The Collection

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

---

1. Visual Gatekeeper (Logic)

"Stop wasting GPU time on bad generations." The Visual Gatekeeper brings a true "Pause" button to ComfyUI. It halts the workflow after an initial generation, allowing you to approve or reject the image before sending it to expensive Refiners or Upscalers.

• Human-in-the-Loop: Grants you manual control over the generation pipeline.
• Clear UX: Large preview with prominent APPROVE (Green) and REJECT (Red) buttons.
• Resource Saving: Instantly cancels the rest of the workflow if the image is rejected.

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.
