Always great to see people innovating on email clients, everyone is different and would have they own best way to manage their email for themselves. So any new option is always good.

Out of interest, you have started with Gmail which is understandable but do you have planes to support order email services or even just plain IMAP?

I know Gmail is complicated as it doesn't really do IMAP properly and so it better to use their api, so you have to chose one of the other to start. But I hope you have plans to support IMAP.
