UV editor small UI change

Hi community. I don't know how about you but I always have a problem to localise my render results in blender. Even, when I was starting using blender I thought the render results just disapear after you go back to the defult modeling. Hence why I would like to propose a small amendment do UI. First - to add to the editor name: UV editor/ Render Results. Second - to add a small chose menu between UV editor and render results. Third one is bit going further. Why there is ony 8 render outputs? Can we have more and folowing that would it be possibe to chose in compositor which output to use?
