Switch topic editing in admin to autosave-on-change with tree-based controls where parent selection is create-only and delete remains explicit. Add public sidebar navigation by topics with sort-index ordering, preserve topic context in photo navigation/comments, and show stable AI/comment badges on catalog cards.
Move 'after photo' upload into the after-preview area with an inline replace action and keep rotations/uploads async so the table stays in place. Clean up autosave helper text noise, remove the redundant back link on photo detail, and loosen sidebar section spacing for a cleaner public layout.
Split comment users and comment moderation into separate admin sections, and add comment search by photo and user for faster moderation. Rework public photo viewing with full-frame repeated watermarking, in-section prev/next navigation, sticky desktop sidebar, and a mobile bottom nav with section return and photo position.
Replace JS-driven loading behavior with a pure CSS skeleton background so gallery cards remain fully native links. Drop click interception and deferred JS loaders to keep photo-page navigation immediate while images are still loading.
Avoid navigation stalls on cold loads by delaying thumbnail requests until cards are near viewport. Stop in-flight page downloads on card click so opening a photo page is immediate even while list images are still loading.
Prevent photo-page opens from feeling blocked while a category list is still loading. Defer thumbnail fetches and lower their fetch priority, while keeping detail images high priority for quicker render after navigation.
Make image loading feedback visible on the public gallery so users see progress on slower connections. Add a lightweight spinner overlay for list/detail photos and clear it automatically once each image finishes or fails.
Keep the sections sidebar visible on the home screen but collapse it on inner pages to save space on phones. Add a menu toggle, overlay close controls, and edge-swipe gestures so navigation stays quickly accessible on touch devices.
