Is there a way to customize the size and number of shortcuts?

I am an editor, which means I do a lot of research. I do not want my shortcuts to reflect all the crap I have to review for work. The latest update shrunk the size of the shortcut squares and added many. That simply does not work for me, and I want to return to what I had before the update. Is there any way to do that? What I have now is a royal pain in the butt.
