Adding context without getting a reply
Brief Rhazes over several messages without it replying to each one, then ask once it has the whole picture in front of it.
Updated
The problem it solves
Sometimes you need to give Rhazes several things before asking anything: a history, a set of results, two attachments. Sent normally, each one gets its own reply you did not want.
Turning it on
The line directly above the message box reads Add context, brief without a reply. Select it and the composer turns copper, the line changes to Adding context, and the send button becomes a plus.
While it is on
Add as many notes and files as you need. Each one is collected rather than answered, and the line above the box counts what you have added so far.
Finishing
Select Done to leave the mode. Everything you added stays in the chat as context, and your next message gets a reply that takes all of it into account.
The status line itself stops being tappable while the mode is on, so brushing it cannot drop you out mid-brief.
