With Kemble open, the app shows what is on screen and the device shows the rest: a direct message in another workspace, a keyword, a reply in a thread you do not have open, and everything while you are elsewhere on a tablet. Preferences’ Send a test is always shown by the device. On a device with several accounts, the number on the app’s icon counts another account only once the device itself has shown one of its notifications.
In Kemble Work, Set a status can schedule one for later, on a phone as at a desk: Choose a start and end time… ends its list of durations, and your scheduled statuses are listed there with Edit and Cancel.
