Quickview close X button

My quickview window is quite large so the X to close it is above the window and out of scope hidden behind the top menu and its not possible to close it. I'm planning on removing some elements from it but would like the option of showing related products or reviews in the window.

Option 1: Can the window be a fixed size but with a scroll bar inside it?

Option 2: Bring the X inside the window into the top right.

(BTW, I think MagePlaza's quickview has both of these!)
