Keynote wish

Tuesday is the Macworld keynote so I'll post my wish. It is pretty much a non-starter I'm sure but it would make life easier. I'd like to have the ability to have Apple Mail re-write the sender of emails. At the very least to display the name I'd prefer it display for people instead of whatever name they might put in. There was a time when "" was just fine. Now that a few years have passed "Bob" is no longer at AOL and now has "" and "" peppered throughout my inbox. It would be great to be able to search for all the emails from Robert and have them show up.
