Users can start, revisit, and delete conversations from the conversation menu in the floating panel. +Messages support copy, edit-and-resend, response regeneration and branch navigation, Markdown export, +helpful/not-helpful feedback, text-to-speech, and browser speech dictation when the browser supports it. +Selecting text in a message exposes a quote action that carries the selected passage into the next prompt. +Files returned by a compatible model can be downloaded directly from the message. +Images up to 1 MB and text, Markdown, CSV, HTML, XML, or JSON documents up to 350 KB can be attached by +using the paperclip or dropping files onto the composer.

The nested menu contains apps, integrations, +boards, widgets, and tools available to the current user.
