The reminders window should be resizable
(Outlook made the same strange mistake)
The column resizing in the reminders window makes no sense (again same mistake as new versions of Outlook)
And the “Dismiss All” and “Snooze All” buttons are in the wrong position
Buttons with non-reversible bulk actions should be HARDER to press (by accident)
In general you should copy the GOOD ideas from Outlook not the BAD!
