In the Send proposal drawer, Recipients is no longer drawn as a box, so each recipient's fields use the drawer's full width. The note under the heading now uses the words in the Role menu: at least one recipient signs and accepts, and someone who reads only can still ask questions. Add recipient sits a field's gap below the last recipient.
Other groups of fields in side drawers, such as New contact when adding a proposal and the accounts in Social's Add account, are no longer boxed either.
