aPlaybook v0.32 beta
Use your mouse (drag & drop) to get the players to their respective positions, the formation you want.
Double-click the player to change the label to whatever you want (e.g. TE).
Added '5-2' & '3-3-5' options for more versatility. The personnel groups buttons transform tokens to squares, triangles and circles respectively. (2012-02-23)
Clicking the 'Reset' button erases all lines from the whiteboard while the current player setup remains unchanged.
Next additions should include predefined standard formations and maybe something else. I suggest (probably easiest) that, until the update, you screenshot your plays and save them as images.
