- PromptInput: attachments and context above the field, the owner's tools and send below; Enter sends, Shift-Enter breaks the line; / offers commands and @ offers context over forms::Suggestions; files dropped on it attach behind a drop veil - AttachmentButton, AttachmentChip with thumbnails and uploads, ContextChips - VoiceInputButton and VoiceWaveform with a red dot and the time - ParameterPanel, SystemPromptEditor, TokenCounter, CostEstimator - forms: a Newline action on Shift-Enter keeps one-line fields to one line; replace_trigger moves beside Suggestions; choose and dropped shared - gallery: composer, pickers and tuning
