New Update Mailbird 2.9.92

[zkSnark]

I am still using v2 lifetime. I like Mailbird only because it provides one Column for the list of all email addresses and another Column to expand Inbox and other folders of each email address. I haven't found this interface on any other email clients.
Is it possible to get this feature on Outlook?

Any e-mail client requiring me to make an account in order to use their mail client is automatically no-go for me. Too big security risk.
