I have to agree with kkolencik. There ought to be a way to remove buttons from the list. I never use the stock buttons. I always make my own. And I have to add lots of them to my projects. The stock ones (and my own slightly faulty do-over buttons) clutter the countertop.
By the way, Rod, who's to say Adobe doesn't read its own user forums? I've worked for other software companies who listen to customers in many ways, for example, at tradeshow booths, via direct email, through user forums, and yes, via web forms.
