I really like airmail, but I think that for the price point there are a few things which could really help.

1. I think that you should improve your search feature. While it is quite standard, unlike some other apps, it can't search for files AND people, let alone with natural language. I think that adding this would be amazing.

2. For me, the main competitor for this app is outlook. I think that you could add a separate pane for google calendars (basically a small google calendars or any calendar pane where you can add stuff and edit in real time) and a separate pane for to-do's. I get the concept of memo and todo in this app, but I don't think that many people write todos in email titles, so that is why I propose this idea. I also think that this could be better if you could choose the app you want to access your to-do's with.

While this is quite similar to outlook, I think that these features would really set Airmail apart from the competition

Thanks!
