I've like to get the date anr/or rev number to automatically update on a board. I can get the date/time to display by placing a >LAST_DATE_TIME or >PLOT_DATE_TIME text on a copper or silk layer, but that uses a lot of room. I'd prefer to just get the date.
I can put a rev number on the drawing as a global attribute, but that requires that I remember to update it consistently. Simply bumping the number every time a file is saved or when the CAM job is run would be really nice.
