1.2.3 10 October 2026

A/B view: the divider can now be dragged directly on the image with the mouse, a pen or a finger; it also has a visible handle. The slider in the toolbar still works.

Trial: after the 10 open images, the next 90 images of the folder appear greyed out with a lock, so you get a feel for the full gallery. They cannot be opened, flagged, compared or exported; clicking one shows where to enter a key.

Trial: the 10 images are now the 10 newest of the folder you are looking at, so subfolder selection, the "Include subfolders" switch and "Hide images without metadata" no longer reduce the count. The folder tree shows all folders with their counts in the trial too.
Fixed: after entering a licence key, the newly visible images were outlined as if they had just been added.

Trial and licence keys: without a key GenLens shows the 10 newest images and keeps export, contact sheets and ComfyUI actions for the full version. A key unlocks the same file. Gumroad keys (verified once online) and vendor-signed keys (verified offline) are both accepted; the key is stored in your home folder and follows you across image folders.
In-app updates: Settings downloads a new version, verifies size and checksum, keeps the previous script as a backup and can restart GenLens on the spot. "Restore previous version" undoes an update. The launchers restart GenLens automatically after an update.

A "back to top" button appears in the gallery after scrolling down. The Home key does the same.

Load in ComfyUI: "Save to ComfyUI" writes an image's embedded workflow into ComfyUI's Workflows panel (Browse → GenLens), ready to open with one click. Works with the full workflow or, for images that only carry the API prompt, in API format.
Re-run in ComfyUI: queue the exact prompt again from the lightbox or for a whole selection; same seed, same settings.
ComfyUI address and workflow folder in Settings, with a connection test. Also settable with --comfyui on the command line.

First release.
Prompt analytics: click any word in a prompt to see how often you use it and how your rated images score with it; word statistics in Stats.
Collections: named sets of images across folders, exportable as zip or contact sheet.
Contact sheets as PNG or PDF with filename, seed, model, prompt, settings or date under each image.
A/B view for two images: slider, flicker and 100 % zoom.
Saved views: store any combination of search, filters, folder and sort under a name. "Similar prompts" ranking from any image.
