Regarding the attachment fetaure, I propose some improvements:

1. bulk upload: many times we need to upload a large number of files and it would be faster to select and upload them all at once

2. the attachments of the email messages (sent and received) should be available in the attachments tab: with the sender name and the message sent date.

3. it should be possible to attach files both from the user computer and the server (the files available in the attachments tab and the files attachd to other emails, if item 2 not available)

4. drag and drop is a big plus too!

Thank you for listening to us users!
