Hi, one thing I've found that is missing (or at least I haven't been able to do) is to select where attachments are to be saved. I suspect they're being saved on phone memory, but people would probably find it desirable to save them to a specific location (e.g. a document into a documents folder in the memory card or a photo under a pictures folder).
Not knowing where they are saved then of course makes it difficult to delete them, and in fact, I'm not sure if once the email is deleted then the associated attachment is deleted as well or if it remains somewhere.
Thanks
