Config file that lets you change the minimum level certain perks can be obtained.

For rebalancing on the fly and to synergize with mods that alter when perks are rewarded. Like Object Renamer, but with perks and level requirements instead of objects and names.

 

Being able to change the skill requirements for perks within the same file would also be really neat, but I'm personally not as interested in that and can't imagine what the inside of the file would look like with that feature implemented.
