A mouse click while the cursor is over the view caption will activate this menu:

Select New View to call up the dialog. Type in a name for the new tab and modify the view properties according to your requirements.

Select OK.
A new, unique tab will be created.

As soon as the first user defined tab is created another tab labelled ‘Default’ will be created. This stores the initial view configuration so you can easily switch from the user defined tab to the default tab.
As new user defined tabs are created their names are added to the Name field on the dialog.

If you select a name from the list a duplicate tab will be created. If you then modify some of the properties the original tab remains unchanged.
If a new view is created by splitting the current view it will inherit an identical set of tabs. Once split, the tabs of the two views can be changed independently.
