Workbook Design Mode
This is a new feature in Version 8 which allows you to make multiple changes to your report without running grids or table. This is useful for large/complex workbooks which run slowly.
It can be enabled through the XLCubed -> Options -> Workbook Options form.
With this enabled you are able to design grids and tables, and edit member selections without needing to run the queries.
Grids and tables will only be run when explicitly told to , for example through the Refresh buttons. Changes to slicers or driving cells will not cause them to be updated.
