Flock has better RSS Reader than Firefox, but one thing that i need is email client. Now im using email client in Opera, and i thing that it will be very good to integrate mail into Flock.

Second suggestion, one thing im missing in Opera or any browser, is massanger. I think it will be great, to open browser and check RSS, Mail and ICQ or MSN at the same time and aplication. It's better to open one aplication like Flock instead 3 or 4 aplications. So integrate Massanger and Email client into Flock, and it will be best browser and I will never use any other. ;)
