I've also got 3 betacoins for Mailbox for Mac. Shoot me a message!
No IMAP facility on the mobile app? :( It is DEAD TO ME. Edit: which is sad because it looks nice.
I know - def a bummer. Luckily, I use Google Apps for Business for imap stuff anyways. But definitely going to be a killer for some people. I assume they're going to be doing imap at some point. It's tough because their functionality really works well with gmail.
ASAP needs for me: 1. Setting to have cmd+r trigger "Reply All" rather than simple reply. This is from my Sparrow days. 2. Hyperlinks in signature - better text formatting of email messages 3. Ability to easily re-order the order of email addresses in to: field. That shits important as sin in the corporate world, but I rarely type them in the proper order the first time around 4. Ability to sort lists by date. WTF
