It would be great to be able to rename attachments when forwarding emails.
Sometimes you need to rename attachments and the only way is to sabe it to PC and then attach again.

This would be very useful even before sending emails. I often use a program that will generate an attachment for Outlook and it ends up being "Exported results yyyy-mm-dd_hh-mm-ss.(file)". It'd be really handy to be able to rename that inline, rather than having to save it, rename it, then reattach it.
