Duplicating projects is a major timesaver if you're dealing with many similar projects. Copy / paste a whole project with the click of a button. An idea could be to have project templates by creating projects, keeping a copy as a Template in the Halted project stage, and then just duplicate it every time you need a similar looking project.
Step 1: Go to the project you wish to duplicate
Step 2: Go to Project Settings
Step 3: Click the options icon at the top right, and select Duplicate project
