Go to Tools, Customize, Command tab, Standard Views category and then drag that toolbar button to the location you want it.
By the way, don't overlook the Normal To icon on the context toolbar that pops up when you select a plane or planar face (or when you use the right mouse button on one of those). Then you can use it without so much mouse movement if this represents some of the cases where you do want to use it.
I hope this helps,
Thank you so much, Jim! That's exactly what I was looking for. And Kevin, I was aware of the shortcut but had just been using the Normal To button and am used to that at the moment. Thank you for the reply though.
You could also use the Ctrl 8 keyboard combination.
