And people monkeying around in there will wind up with a dead phone.Because they want it to be simple enough for Non-techie people to use. Sadly the only option you have is iFile from Cydia (Jailbroken App Store).
This allows you access to the whole system folder of iOS, and you'll see it's a horrifying, confusing mess.
iOS is a closed source OS and Apple would rather have a walled garden than allow people modifying stock things and adding / changing things that they didn't intend on them doing.Well, I'm not gonna jailbreak. I don't want to void my warrenty. Why does apple not allow visibility?
