[Feature Concept] Semi-transparent, on-toggle full screen map

Hey guys I have an idea of a feature that would be good design I think. When you press a key (Toggle), say 'T', it prints a fullscreen map over the basic UI that would either be 50% visible or that only has the edges of the map, no color inside the edges, and you see more details on that map than on the regular mini-map, like champs' levels, health and mana. Would be easier to check your map 'cause having a big UI is so bad for the gameplay, and not everyone has a huge-ass screen or TV connected to their PC so they can turn the UI to the smallest, plus we barely see the global positions of the champs on the minimap. Thank you for your time ^^.
