I’ve been a K9 user for years.
I manage 30 email accounts with it. (ISP)
Please bring back these features:
- Account Overview
- Update all button
- Buttons at the bottom
Account Overview is the most important, as
it allows at a glance to see whether a certain mailbox (out of a list of 30!) has new mail.
This saves time versus checking multiple areas or wading through a unified mailbox.
This was a major productivity feature.
