Adding also to my previous post: 3. the notification LED not blinking for new mail, which makes me check every few minutes if I have mail and I missed the sound.
4. selecting a folder could be implemented differently; i.e allow navigation and the use of the search function - like the search in the inbox
5. in the options for sorting messages in a folder, would like also to have sorting by subject.
On the other hand, congratulation to the guys for building such a nice interface. Reading mails is really clean and fast. Thanks already.
