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.

For anyone else confused why Ctrl+F doesn't work, that PR was closed without being merged

[Jardo-51]

This would be nice to have.

Heads-up: the earlier “Implemented in #1501” note is incorrect — #1501 was closed without merging (merged: false). In-thread Cmd+F still is not in the shipped app. Keeping this discussion as the open tracker (see also #10159, closed as duplicate of this).

I'd like this on web and desktop. In a long thread, I want to find an earlier message or code snippet without scrolling through the whole conversation.

Ctrl+F / Cmd+F should search the current thread, including messages outside the rendered viewport, highlight matches, and let me jump to the next or previous match with a counter. Escape should close the search.

The existing Ctrl+K / Cmd+K search helps locate threads, but finding each occurrence within the thread I'm already reading is the part I'm missing.
