Hi Chuck,
I haven't looked at the drag and drop so I can't help on that one.
As for the header, I go to the Data tab on the Planner settings, select the column header [Right Column Headers], choose Properties, and select the Content tab. In the Content field I place the following code:
CHOOSE(loc:date % 7 + 1,'Sun','Mon','Tue','Wed','Thu','Fri','Sat') & ' ' & DAY(loc:date) & ' ' & SUB(Format(loc:date,@D4),1,3)
Which gives me a column header that looks like: Sun 13 Oct
of course you can use whatever dat format you wish.
Regards
Parker
