Need to add community members who can take over maintenance and enhancements.

[richlysakowski]

I just tried to create a Pull Request to merge updates by community members, but I go an error message that I could not submit a pull request because of lack of privileges for this repo. There are MANY maintenance changes and enhancements by the users of this package that should be merged into the main repo. Streamlit has changed a lot in 2 years, and updates have not been merged in 2 years. Please let community members do these badly needed updates. Thank you for your great work in providing this demonstration code.
