What I'm asking for is a mod that allows you to see your current stats while in game so you don't have to go into the skills menus just to check how much magic/stamina/health you have. This could tell you exactly when you have enough magicka to cast a certain spell, and it definitely gives you a better sense of how close you are to dying. It could show you how fast you are regenerating, and it could also alert you if any stats are red (damaged due to disease or poisions, etc). I haven't seen any mods like this, but in theory it doesn't sound difficult to make, but would be a major convenience.
