Suggestion: Show conversation title in the mobile header
On both the ChatGPT mobile app and mobile web, the header does not show the title of the conversation currently open.
This is especially confusing on mobile web when returning to an old browser tab or restoring a page from browser history. The correct conversation opens, but there is no immediate indication of which conversation you are in without opening the sidebar.
Suggestion: Display the current conversation title in the available header space, with an ellipsis for long titles.
It seems like a small UI change that could significantly improve navigation and orientation, especially for users with many conversations.
