Setting definition properties manually
We’ve talked about definitions and configurations in the previous topics in a developer context. But how can a regular user modify those values and change the behavior of the backend UI? Well, you might be familiar with the Sitefinity advanced settings screen. It is available through the Administration -> Settings -> Advanced menu in the backend.

The screen displays a tree of settings that can be modified. All those are under a root node for the specific area. Guess what – many of these are the exact same configurations that persist definition values. By changing values in the advanced settings screen, we are actually changing persisted definition values.
