Hi,

I'm looking for a mod that allows me to set/select my skill modifiers when I level up.

I'm playing this game through again after a fairly long break. I remember the worst thing about the game was leveling up my skills so I would get a x3 or higher skill multiplier. Surely there is a mod that will just let me do this without all the micro-management.

First hit with "modifier" on tesnexus: http://tesnexus.com/downloads/file.php?id=2691

There are also mods like:
nGCD and Progress
Realistic Leveling

that change the way leveling is handled(and get rid of that micro management also).

http://tesnexus.com/downloads/file.php?id=9914 let's you customize the modifiers, and by default cements the modifiers based on your specialization (magic, stealth, or combat), and a selected secondary specialization... but as I said it also allows you to set them yourself.
