All template files available in your version can be accessed and changed directly within the editor. Every file you open in the editor has three tabs that let you keep track of your edits, access the file's details, and edit the file itself.
Diff view
This tab lets you see all the edits saved for the selected file. The original file is always based on the latest default file within your version.
You can easily revert back to the default file by clicking on Reset my file.
File details
This tab lets you access all the details of the selected file, including its URL. You can also enable and disable custom components from this tab.
Code editor
This tab lets you edit the file's code. If you're replacing an existing component, the default component's code automatically populates the editor.
