Finally we're getting close to releasing the new and improved Web Mail interface, and some very nice new features based on your feedback.
I'll be providing more details about which new features get included in the first round when we get close to the release date. The obvious change is a much more usable layout, with tasks on a toolbar at the top and a re-organized folder tree. There will be some other goodies too, so stay tuned. Some of what might be included is listed in this older post, when 6.0 was just a concept. We've refined it a bit since then.
