Below are the instructions that you have posted for dragging and dropping a file into a new email.  I wondered if you could please add a feature that would allow us to drag and drop files from email to email.  Sometimes we need to forward an attachment, but there are other attachments from that same email that do not need forwarding.  We'd just like to be able to move the file we need over into a new email.  We had this feature prior when using Outlook.  Thanks!

Drag and drop from System*:

1. Open the composer window.
2. Choose the files to be attached.
3. Drag them into the Composer window .
4. A box with the text 'Drop files here' appears.
5. Drop the mouse cursor inside the box.
6. The files dropped get attached to the mail.

* The Attachment Drag and drop feature and attach multiple files feature are supported in the Firefox 3.6 and above, Chrome 6.0 and above only.
