Add direct Delete action to Codex chat menu

Codex chats currently have to be archived before they can be permanently deleted from Archived chats. Please add Delete directly to each Codex chat’s context menu, with a confirmation dialog, while retaining Archive as a separate non-destructive action.

Hey @michael.zolotarevsky! Archive and Delete aren’t really interchangeable, so it makes sense to keep both actions directly available in the Codex chat menu.

Right now, permanently removing a chat means archiving it first, opening Archived chats, and then deleting it from there. That feels like extra work when the user already knows they want the conversation gone.

A direct Delete option with a confirmation prompt would make the flow much cleaner while still protecting against accidental clicks. I’ll pass this suggestion along internally, though I can’t promise a timeline for any changes.
