Fixed

Buttons no longer appearing on video thumbnails — caused by YouTube's UI overhaul in May 2025 which migrated the home feed and subscriptions page to a new yt-lockup-view-model component system. The script now detects both the old (ytd-thumbnail > a#thumbnail) and new (.yt-lockup-view-model__content-image > a) thumbnail structures simultaneously, with a fallback for any remaining edge cases.
Thumbnail buttons were being clipped by overflow: hidden on parent elements — fixed by attaching buttons directly to the thumbnail anchor link instead of the thumbnail wrapper, and triggering hover visibility on the whole video card rather than the thumbnail alone.

✨ New

Collapsible panel — the control panel can now be hidden via the "Hide panel" button, collapsing to a small floating icon in the bottom-right corner. State is persisted across sessions via localStorage.
Dim watched videos — when "Show hidden" is active, already-watched videos are visually dimmed (reduced opacity + slight desaturation) so they're immediately distinguishable from unwatched ones.
Smooth button reveal — thumbnail buttons now fade in on hover with a subtle slide animation instead of being always visible.

💅 Redesigned

Control panel rebuilt with a dark glass-morphism style — blurred background, consistent border radius, icon + label buttons.
Thumbnail buttons use a cleaner pill style with stronger shadow for readability on any background color.
