I'm the opposite. I actually like having a separate hidden screen for my inventory, equipment, map, etc that I have to bring up. Kinda like actually having to look in your pack. You may know what is in your backpack for instance, but you can't actually see what is inside of it constantly all the time. If you don't remember, you open it up and look inside.
And I much prefer to have my view of the dungeon fit the whole screen or at least most of it like crawl, rogue, nethack etc.
