New Undercover Tonneau

After much consternation about which hard cover to go with, I finally decided on the Undercover. It fits great and was easy to install. The mounting bracket covers part of the front stake pockets. I am thinking of notching the bracket so I can use my bull rings when the cover is off. Any downside to doing this?
Also while I am asking questions, I would like to put some kind of divider in the rear of the bed to hold groceries, etc. Any recommendations on which one to get? It needs to be easy to install and remove.
Steel horse/VDP used to have some really nice pieces that replaced the stock covers and would only need to be relieved so you could move the hook up and down.
The nicest divider I have seen is Loading Zone's, Loading Zone - The Original Cargo Gate
It has a cam'd side that releases with a flip of the handle, but they were getting too expensive the last time I sold one. Keeper makes some cargo dividers, ratchet and shower curtain style.
