I have only been modding for a few weeks but I already ran into an issue; some of the minor things I wanted to change did require me to mess with lots of files. That in turn increase the chances my mod would not be compatible or override some aspects of other mods. What I propose is to add a mean to make tweak mods that allow to make broad changes (like 20% more weapon damage or 30% more FIDSI and such) without the need to actually change individual files. I believe I seen that in some other games, but I don't remember wich.
