Search & multiple windows
- Search reaches all your windows. Filtering now also surfaces matching tabs from your other windows, grouped under a clear "Other windows" section.
- One-click window-scope toggle in the search bar — flip between this-window-only and all-windows without hunting through a menu.
- Color-coded windows. Each window gets its own stable color and shows its active tab's title, so tabs from different windows are easy to tell apart at a glance.

The tab list
- The list follows your active tab — switch tabs anywhere and the current one is highlighted and scrolled into view, with a quick "jump to current tab" control.
- Background-opened tabs now appear in Recent, labelled with when they were opened.
- Hover a tab to see its age in the main list.

Settings & controls
- New "Quick settings" gear menu right in the popup: switch between highlight and filter, show or hide unloaded tabs, and (in the popup) whether picking a tab closes the list — no more digging through the options page.
- Search niceties: a clear button, auto-focus when you open the extension, and per-view highlight-vs-filter.
- Cleaner right-click menu that behaves like a standard context menu.

Performance & reliability
- Handles very large sessions smoothly — thousands of tabs, much faster view switching and searching, and no more freezes when filtering across windows.
- Steadier closing and scrolling — closed tabs no longer flicker back when you close many quickly, and the Recent list stays put across restarts.

Polish
- Native OS font, a clearer toolbar icon, and reverse hover-scroll zones for quicker navigation.
