Make annoying datamerge save warning userfriendly
The warning window "You must turn off the data merge preview before you close the document..." must be changed. Its good to have straight hint what's have to be done by user, but in modern software we
need a better approach.
Like button "do it for me now and we continue" and even checkbox "always do that and never ask again" (ofc with undo somewhere in preferences or datamerge interface, see screenshots)
