Similar to how the Nature and abiility icons have a hover over in the battle menu, I think adding one for UV would also be helpful, one less page view.
I don't think it's necessary, please explain more

Currently, to view the unique value of mons while in battle, you need to click on the Show monster detail button, which opens up a new window. Sometimes this new window can be confusing if you have other tabs open in that same new window ( Firefox ) , as the monster detail page will open in the first tab and sometimes not switch.
My idea is to add a new unique value hover over button to the main monster battle page.

My idea would be to add the hover over button that nature has, showing the same UV total that the monster detail page has:
