Due 23.1 for macOS is now available. This update brings two changes.
First, the 12 Quick Access Times buttons are now mapped to the following keys:
1, 2, 3, 4
Q, W, E, R
A, S, D, F
and they adapt to your keyboard layout accordingly.
Second, there is an under-the-hood change which prepares Due Mac to handle an upcoming database change that enables selective critical alerts on iOS devices.
