If you find yourself using the same layout, with the same stickers and settings, you don't wan't to waste your time adding and configuring them everytime. StreamLadder has a features called "Templates" which allows you to save a layout, with all it's settings, to be reused for other clips.
The data that is saved in the template is:
To save a template, on the final step of the editor ("Export"), click the "Save Template" button
You'll be prompted to enter a name for your template (e.a. "Warzone Split")
After saving your template, next time when selecting a layout, the saved template will also be there. Once clicked, it takes you directly to the final step with all saved data applied to your clip!
