Hi Stef,

A FastTable can have a function to extends it. For example a Search or a
Filter. By default this function is not explicitly shown to the user.
For example in Nautilus the user have to know he can type the name of a
method in the list to search a method.

With beExplicit the functionality is shown to the user. For the search
and the filter there will be a text field added to the FastTable.
