apps/web

Problem or use case

Can we have a search with cmd + F within the thread like the Codex app has?
Also, a search for the thread's sidebar would be awesome, found this issue mentioning it but not the in thread search: #1043.

Proposed solution

Search within the theards/chats to find something in the conversation without having to scroll and eyeball it.

Why this matters

Its very hard to find something by scrolling up in the thread, especially while its in middle of generation.

Smallest useful scope

Search/Find text in the thread.

Implemented in #1501.
This adds in-thread find/search in apps/web with Cmd+F / Ctrl+F, inline match highlighting across thread content, virtualized row navigation, and follow-up polish for highlight consistency and search performance.
