As you work in the Editor, your work is saved automatically and continuously. This is so you can enjoy uninterrupted work and not worry about losing any changes made to your program.
The only exception is when you edit any component of your brand configuration. Then, you do need to click Save to save your changes.
Saving edits to your brand configuration is not automatic because these edits apply to all programs using the configuration. Any change you make affects both current and future programs as well as programs created in the past (when they are published with a new version). We therefore recommend proceeding with caution.
