Internet Explorer 7 — the 2006 comeback
The browser that finally brought tabs to Explorer. Round glass Back / Forward "pearls", a full-width address bar with the live site favicon, a dedicated Live-Search box, and the command bar on the tab row — Home, Feeds, Print, and working Page and Tools menus. Original toolbar icons throughout, plus a faithful "About Internet Explorer 7" box.
Windows Vista Aero glass
A new title-bar style in Settings ▸ Title bar: a translucent, blurred glass caption with the Aero bevel, glossy caption buttons and the red close. Switch it on for any Windows theme to frame the window in 2007-era glass.
A Vista scrollbar to match
The web view's period scrollbars gain a Windows Vista / 7 "Aero" look — a pale, glossy blue-white gel thumb with slim chevron arrows — lighter and rounder than the XP Luna bar.
Fixes & polish
Tighter Vista glass (a touch less transparent, a stronger frame bevel), a solid backing so new tabs never flash through to the desktop, and a range of theme touch-ups.
