Ohhhh ok, too bad, kinda go my hopes up there, hate having 30+ headers that if i need to make any change i have to do on all of them.
I try to minimize that by setting up a button bar where the "common to all" buttons are located on the left and the "layout specific" buttons are on the right or in a second row. Then an update is sometimes no harder than updating one layout, copying the buttons to the clipboard and then flipping through the layouts deleting and pasting to drop in the updated buttons.
You might find it interesting to examine the design of the navigation buttons I put on the top of my layouts in this demo file: http://www.4shared.com/file/dZ0bjclw/ManyToManywDemoWExtras.html
I created them on one layout and then copied and pasted without making any additional changes to them to put them on all the layouts.
