Templating feature for "Pro Sites" plugin

Recently I started a new project and made a simple front-end dashboard with MDL and I used Pro Sites in this project.

Unfortunately with all the advanced features of this fantastic plugin, it doesn't have any structure to create templates by the users and made a different layout with CSS frameworks like Bootstrap, UIkit, MDL or any other frameworks.

In this case users just can change some CSS styles, and it's impossible to change layout. So I suggested to the "Pro Sites" developers and support team, Please Please Please add this feature to this lovely plugin and make me and other users happy.

Thanks WPMUDEV Team.
