Condition Statement Builder?

Could you give me some ideas/example on the "I build settings page that other employees can use to adjust application behavior"?

It really comes down to the project you are working on.

Our business needs are not that complicated, so we don't have to implement filtering like you were describing.

I'd say start from figuring out what the business needs might be. Building a complete condition engine takes time, but also, it would put pressure on admins to use it the right way, to the simpler it is designed to be, the easier it is use and build.
