Enhanced Scheduled Notifications
The new scheduled notifications are a fantastic addition. However this could be further enhanced by allowing several scheduled times for receiving email throughout the day, instead of just the one.
A popular idea for being more productive with email is to schedule in only 2 or 3 times a day where you deal with it.
This enhancement would build on this brilliant new feature and take the app to another level.
To expand, it would be great if schedules could be created per folder, and if the times could be set per day. I.e., M-F I get mail from a certain folder from 8-5, but on Saturdays/Sundays it's silenced all day.
