There are a number of ways to manage the sections in your proposal. When you select a section the section management icons will appear on the left of the section. From here you can:
Deletes the current section you are in.
Adds a new empty section to your proposal.
This allows you to browse previous proposals and insert modules from a proposal you have previously created. When inserting a section from another proposal, the content will automatically take on the global typography styles you have set in the current proposal.
Duplicate the current section you are in.
The sidebar allows you to view a list of all of the sections in your proposal. From here you can drag and drop to reorder the sections of your proposal.
