- Add TextLineCount node: counts lines in multiline text input - Add SaveAudioSilent node: saves audio without being a terminal output node (for for-loops) - Fix fetch button: use addDOMWidget() API for Vue frontend compatibility - Fix Civitai API: add Accept-Encoding header to avoid Brotli decode errors - Add button hover highlight styling - Replace canvas-based preview with DOM-based rendering
ComfyUI KaiUtilities - KaiCivitaiLoRALoader
A ComfyUI custom node that extends the built-in LoRA Loader to fetch and display Civitai metadata, including trigger words and preview images.

- Full JSON Output: Exports complete Civitai metadata as JSON string for downstream nodes
- Preview Images: Displays preview images directly on the node with pagination support
- NSFW Blur: Automatically blurs NSFW preview images (click to toggle)
- Local Caching: Caches Civitai metadata and preview images locally with 7-day TTL
- Concurrent Deduplication: Multiple requests for the same LoRA are deduplicated automatically
