I want to modify the game such that all skills will contribute to my characters level up, like in Skyrim, as opposed to just having 10 preset skills. Is there anything that anyone knows of in the editor that can be worked with in order to allow each skill to contribute to the level up progress regardless of it being major minor or other? Thank you!

iirc not without OpenMW.

Madd Leveling

However, these all have their issues, and will interfere with other mods that even look at the leveling aspect of the character.

I never worried about my starting skills to be honest. By Level 10, your character is what it is going to be no matter what you have picked in the beginning. I just pick a skill from each governing attribute and it all balances out in the end.
