The main window is divided into four panels, as numbered in the screenshot above.
- 1: the quick selection panel contains a tree view that provides one-click access to dynamic lists of messages.
- 2: the current list of messages, or results list, typically obtained by clicking on an item in the quick selection panel or by the command.
- 3: the contents of the message that is currently selected, if any.
- 4: the tags panel, to add or remove tags from the currently selected messages. If not needed, it can be hidden by unchecking in the menu bar.
