How do you organize your Selenium scripts?

How do you organize your Selenium scripts in Git branches?

Assumption #1: You have a separate repository for Selenium scripts managed by QA.

Assumption #2: You have multiple configurations of your product. They need to be tested separately.

Do you still have "master" and "develop" branches?

What is the meaning of those branches? Do you select one configuration and make it default?

Do you keep feature branches for each configuration forever?
