	273	Dropping a thread from another environment attaches a saved transcript file. The source
	274	environment must be connected and up to date. The transcript includes the visible history and
	275	saved text context at the time of the drop; later messages and the contents of attached files
	276	are not copied. The agent can read the saved transcript after the source disconnects. Normal
	277	file attachment limits apply.
	278
273	279	Images keep their thumbnail shelf above the text and also get a chip at your cursor, so you can
274	280	say exactly which image you mean. Deleting an image chip leaves the image on the shelf; removing
275	281	the thumbnail asks first when the image is still mentioned in your text, then removes both. Files
