The Extensions tab of the XLL+ Function Wizard shows in detail all the function extensions that have been registered and are available for use with the current add-in function.
The tab will not be visible if no function extensions with parameters have been registered.
A list of all the extensions is shown on the left of the tab. If you check an extension, then it will be added to the function.
If the extension has any parameters that need to be set, these will appear in the property grid on the right-hand side of the tab. Any descriptions and display names that are contained in the extension definition will be displayed as help in the grid. If the text was localized in the extension definition file, then the help and display names will appear in the language of the user.
