A specific arrangement of user
interface components is defined as a perspective. In general, a
perspective always consists of several views. A perspective can be customized by
right-click on the open tab in the perspective bar. Inter alia it
can be saved, closed and reset to its starting point.
The 
on the toolbar can be used to
close a perspective. Editors like the XML Editor are close relatives to
perspectives, with a few differences:
Unless re-arranged, all editors open in a central area typically in the middle of the screen as tabs stacked on top of each other. Editors have to be part of perspectives, otherwise they get closed. While you typically have one view whose content depends on the selected Object, you can open a separate editor for each Object you want to edit. The editor will stay open until you explicitly close it or the Laboratory itself. Editors can contain unsaved content. In this case their tab is marked with an asterisk (*).
