Since this is an After Effects template, "creating a feature" typically refers to adding a new scene or functional element to the presentation. Here is how to do it:

: Go to the project panel, find a "Scene" or "Media Placeholder" folder, right-click an existing scene, and select Duplicate .

: Open your new scene, replace the screenshot/video in the placeholder with your specific feature’s visual, and edit the text layers to describe the new functionality.

: Open the project and find the Main_Render or Master_Comp .
