Hey, thanks for the feature request. This is a popular request, and users have asked for something similar in other threads: Ctrl + F not working in Chat/Agent panel for long conversations (Feature Request: Dedicated Chat Search), Request for Ctrl+F Search Functionality Feature in AI Agent Chat Transcript Window, Search text in the Agents chat, so you’re not alone.
Quick status update: search currently only matches chat titles, not message content, so it can feel like the scope is limited. Full-text search inside long conversations and message-by-message navigation are on the radar, but I can’t share an ETA yet.
