If your minion groups are on these datapads/notecards, however, just flip each one over as that minion group acts. With open initiative, it can be tricky to keep track of both how many slots have been used and which NPCs have used those slots. Minion groups in particular are useful at the table. The datapads themselves are designed for stat blocks: minion groups, vehicles, and weapons. Americans may be stuck with letter and legal paper, and the former doesn't fit a 4-by-6 inch notecard very efficiently, but you'll have to pry those points, picas, inches, and factors of 12 from my cold, dead fingers. I recommend that those who, like me, use US paper sizes use the legal paper version if they can: it fits four notecards rather than three and most print shops here charge the same for a copy made on either size. Weights/densities of paper equivalent to stiff, sturdy index cards one can buy in an office store are also specified in these presets. Printing instructions for presets are included in each document. If you live in the rest of the world where paper does that cool resizing-ratio parlor trick. There are also versions that print A6-sized notecards on A4-sized paper.
The download is a zip archive with 4-by-6 inch printable index cards that fit on letter or legal paper. These printable datapads have seen extensive use at my game table, and I've finally put them together in formats that should be useful to everyone. (The download link is at the bottom of the article.)
