UX improvement suggestion – full-width layout for messages and chat

Hi,
I’d like to suggest a UX improvement: currently, in both the message areas inside "Merhavim" and in the chat interface, the messages appear in a limited-width block with large white margins on both sides.

This creates a cramped feeling and doesn’t make full use of the screen space, especially on wide monitors.
Is it possible to make the layout fully responsive so that the messages stretch across the full width of the screen (with proper inner padding)?
It would significantly enhance the user experience and visual flow.

Thank you in advance 🙏
