Hey @mfortman11

How are you?

How does this work on pip install? Will these be added on the build step or will the user be able to change later as well?

Hey @mfortman11

I was going to ask the same question as Ogabrielluiz.
How are we going to change those variables ENABLE_SOCIAL_LINKS and ENABLE_BRANDING ? Can we change them in the .env file https://github.com/langflow-ai/langflow/blob/main/.env.example?

@codenprogressive You can set this flags from src/frontend/src/customization/feature-flags.ts file.
