Let me just add another voice to the chorus of "please give us data merge!" Not only is the merge function itself necessary, but the ability to generate cut-stacks would also be lovely. That is, once the print run is complete and ready to trim, the first position of the stack is, say 1-500, second position is 501-1000, etc. I.e., the first sheet would have record 1, record 501, record 1001, and record 1501; sheet two would have records 2, 502, 1002, and 1502; and so on down the stack. This kind of thing is absolutely essential for maintaining the order of pre-sorted mail lists on things like postcards. Right now we use a third-party Acrobat plugin called FusionPro for that, but it would be very nice to have everything in one place.
