You can use two types of collections:
Standard collection: You create this collection manually by adding and removing files to create a custom list. For example, a standard collection could be a list of your first three chapters to use as a compile source for exporting a partial manuscript (see Chapters 12 and 13 for more on compiling). Or you can make a collection list of all scenes that follow a particular subplot within your storyline. You can even use a standard collection to try out an experimental scene order.
