Some of my map documents (MXD's) are used as "base maps" which are pre-configured for certain situations. These base maps are adjusted (area of interest, page properties, layers, etc.) and "usually" saved to a folder for that project.
Sometimes, I would like to simply revert to the "base map" again, but to do so requires exiting the application and reopening the base map. Having the option to close and reopen the current map document would be quicker. Thanks.
