While I usually roleplay and always use solely immersion mods, HUD is something that I love having around and was amused by lots of on-screen info ever since I was a small child. 
Is there any ini setting that would let me have things like HP, MP and fatigue bars always on instead of vanishing? I also wouldn't mind at all if level-up bar would always be present. I also take mod suggestions but those mods should be compatible with Less Intrusive HUD and Immersive HUD.
Thanks in advance!

Anyway, thank you for suggestion, but I'm using that already and as far as I know it doesn't offer an option for having things on screen permanently, only to have things on screen much shorter or not having them at all (which I use for removing the comapss).

Just checked, have the latest version anyway. I'll see if I can find anything in the inis (why couldn't they stick everything in a single one like in the past :s).
