With Flexitive, you create versions of your designs by duplicating them. By creating versions, you can view and explore ideas within your team's designs, without worrying about overwriting your original work.
To duplicate your design, click the Duplicate option beside the page on the home screen. This will create a new design that is an exact copy of the previous design with the naming convention original-design-name 2.
If you want to move a design to a different folder, see here.
