Image MetaHub v0.19.3
[0.19.3] - [09-12-2026]
Added
- Prompt Library: Save prompts from your library into a dedicated collection, then search, sort, copy, remove, or jump back to the source image. Random lets you rediscover saved prompts with their positive and negative text and source preview.
- Image Provenance: Added a read-only provenance view for inspecting available source and lineage information, with on-demand SHA-256 fingerprinting and copyable provenance summaries.
Improved
- Image Viewer Navigation: Arrow-key navigation is more responsive, with better neighboring-image preloading and smoother browsing while moving quickly through images.
- Viewer Zoom: Choose Fit or 1:1 as the default image zoom. Images configured for 1:1 open directly at their native zoom, and mouse-wheel zoom uses more consistent increments.
- ComfyUI Workspace Navigation: Viewer navigation from the ComfyUI workspace follows the workspace's newest-first order independently from the main Library sort and stays current as new images arrive.
- Library Startup and Refreshing: Library caches remain valid across launches when their parser version matches, while startup enrichment and background refreshes perform fewer unnecessary recomputations.
- Thumbnail Loading: Failed thumbnail decodes are cached for the current file version, avoiding repeated decode attempts while browsing.
Fixed
- ComfyUI Krea2 Workflows: Prompt, negative prompt, and LoRA extraction follows the executed Krea2 workflow route, including grounded encode nodes and switch-based workflows.
- Detached Viewer on macOS: Packaged viewer windows load application paths containing spaces or Unicode characters correctly.
- 3D Model Preview: Switching between 3D models recreates the preview for the currently selected item.
- Library Cache Persistence: Compatible parser caches are reused on subsequent launches instead of triggering a full library reindex.
- ComfyUI Workspace Thumbnails: Single-clicking a thumbnail opens it in the workspace inspector, while double-clicking or pressing Enter opens the configured full viewer and keeps the workspace active.
- Detached Viewer Deletion: Deleting the current image advances directly to the next available image in the same viewer window.
- Image Grid Deletion: The image-grid context menu includes Delete, applying to the clicked image or the current multi-selection.
- Light Mode and Viewer Themes: Text, headings, surfaces, and viewer actions maintain appropriate contrast across Light, Dark, Dracula, Nord, and Ocean themes.
