The message box’s + menu has Dictate. Speak, press Done, and your words land in the box for you to edit before sending. They are transcribed on Kemble’s own server, the same way voice messages are, and neither the recording nor the words are kept.
Scheduling works in a direct message kept in the other person’s organization, and partners can see the channel name on their drafts and scheduled messages in a shared channel. Scheduled messages, drafts and to-dos now update on every device you have open, and Todos › Clean up › Clear completed can be undone.
A mention in a thread stays new until you read the thread, /shrug reads exactly as typed, a message you schedule for a channel where only admins can post is refused right away, and Send and follow up is offered in shared channels.
