Advanced configuration options not (yet) available in App Studio present an ideal opportunity to divide the configuration work up and having team members with differing experiences working on parts of the solution. Taking User Interface configuration for example, often you will find that only a small component of a User Interface requires advanced configuration. 

Have a professional developer implement the advanced configuration using Dev Studio in its own (potentially reusable) Section rule. Meanwhile a Citizen Developer can then work on the more typical UI configuration in App Studio, adding the advanced component as a "Section include" when it is ready.

This approach encourages building reusable componentry, whilst at the same time appropriately utilizing the differing capabilities of your team members to complete the feature.

Discussion on this topic was sought from the LSA Data Excellence (Pega 8.4) webinar conducted in July 2020. The webinar and its full set of discussions that arose from it are available at LSA Data Excellence: Webinar, Questions & Answers.
