Unfortunately new Metronic structure is too confusing and the document is not enough. we have to do a lot for simple customization.
Metronic's new structure is designed to boost the development process by using the latest tools available now. You can see that a lot of customers rated 5 stars the Metronic's Customizability. Every developer has different level of coding and easy or complex is very relative thing in this context. However we made sure that our documentation provides with all the details to help our customers in getting started in the shortest amount of time. Our support is always ready to help when you have any question beyond the documentation.
