How to edit toolbar

I know how you can customize the toolbar up top and add the tools that you use the most, but is there any way to remove the default tools that I don't need and are taking up space?  I can get to my custom tools by clicking the little ellipses, but that is an extra button click rather that if I could just remove some of the default icons that are taking up toolbar space.  I know one click doesn't sound like a lot but when you are working with hundreds of PDF"s a day it adds up.  I would like to remove the "show next page" buttons as well as the zoom buttons to make room for tools that I use way more often.  Thanks for the info!
