Once you install Tab Scope, a popup will open when the mouse pointer is hovering over a tab and you can see the real-time preview of the tab contents.

When you move the mouse pointer from a tab to the next one, the popup moves with animation effect. The animation is configurable in Options, and you can change the speed or disable it completely.

When the mouse pointer is hovering over the upper side of the popup, the toolbar will appear and you can navigate (back / forward / reload / stop) the tab contents, pin as app tab, view Tab Groups and close the tab.

If you double-click a blank space of the toolbar, it will disappear temporarily. This helps you to directly click a link which is under the toolbar.

Click the magnifying glass icon or right-click on the preview to toggle its zoom state.

The popup zooms with animation effect. The animation is configurable in Options, and you can change the speed or disable it completely.

If you are using Tree Style Tab or Tab Kit add-on and display the tab bar vertically, Tab Scope opens popup on the right side of a tab.
However, you need to set [Alignment of popup] to [Auto-detect] or [on the right side of a tab] in Options.
