I looked into it and it's a bit similar, but functionality isn't exactly the same. JIP-CCC allowed to turn FNV into tactical shooter (not very good tactical shooter, but still) NFF is a mod that makes herding multiple followers easier, but still feels somewhat restricting after getting used to CCC. Also, can't find ANY mod that incorporates functionality similar to Convenient Companion Inventory (adding free companion inventory capacity to main character) It's one of those small mods that once you tried it, you can't believe you once could play without it.
