This toolbox can be opened via the Window > Standard Toolboxes menu.
The toolbox contains the following pages
TIP: Some of these pages might be hidden, to simplify the appearance of the Impact Explorer. You can get them back by right-clicking on any of the pages, choosing the Explorer Pages item from the context menu and unticking the Hide Tabs option.
Use the tabs to switch between pages. You can right-click on the tabs to access the context menu, which allows you to control Tab Position (Left, Right, Top, Bottom, Hidden) and Tab Visibility (including whether text labels are displayed alongside the icons).
