What is the difference between reduced, complete and maximum features under the config section?

This configuration parameter specifies the extent of the JDom classes to store in your project:

Reduced - the bare minimum. For example, if you only load an image type field then only this JDom class gets packaged (with any dependencies of course)
Maximum - all possible methods/functions added to controllers/models, all possible classes & helpers added
Complete - Entire JDom - good if you want to extend anything and need to avoid potential namespace collisions in future:

Hope it helps!
