Hi

With this new version, please give us the markdown to remove the vertical space at the top of the sidebar.

I don’t think anyone appreciates this initial space at the top in either the sidebar or the main content area.

Thanks

Cheers

Found it: Just adding it here in case anyone needs it:

st.markdown(" <style> div[class^='st-emotion-cache-10oheav'] { padding-top: 0rem; } </style> ", unsafe_allow_html=True)

Adjust 0rem value as needed.

Cheers

Love the new st.link_button and the long awaited st.rerun… but I cannot be happier about two of the notable changes: empty state for every input and the st.download_button not opening new tab! :star:

Two questions for the future
I look into the roadmap, but I can’t see anything related to these two features for the st.date_input

  1. Localization (optional languages)
  2. Week starting from monday (as an option to the sunday-first week)

New bug I encountered: renaming a tab after using st.rerun get the script to the first tab.
Link to the topic HERE.

As always, love the framework and his magic, keep up the awesome work! :heart:

Hello Streamlit community!

I’d like to suggest an idea inspired by YouTube’s model, to allow app creators to monetize their applications

App Access Payment Gateway

  1. Payment Structure: Allow users to choose to pay for different periods of access to an application.
    This could be:
  • One day
  • One week
  • 15 days
  • One monthFor instance, if someone wishes to access a specific application, they might do so by paying, say, $0.50 for one day of access.
  1. Facilitating Monetization: Now that Streamlit, under the Snowflake umbrella, has the capability to handle complex infrastructures, it could take care of the ‘heavy lifting’. This includes but is not limited to:
  • Database optimization
  • Transaction management and payment security
  • Maintaining the already efficient framework that allows us to deploy Python apps on the web
  1. Revenue Sharing: Streamlit could take a percentage of the revenues generated from user payments, much like how YouTube does with ads. The remainder would naturally go to the app creator.

I believe this suggestion would not only benefit app creators looking to monetize their work but also assist Streamlit in generating additional income, thereby strengthening the entire ecosystem.

What are your thoughts? I’m open to feedback and further developing this idea with everyone’s input.

Thanks Fer,
