Sounds similar: I would like to see things other than emails live within my email inbox. You click on a "subject line" in your gmail table view, and it opens up a to-do list, or a wiki, or a spreadsheet, or a regular old email. Not an email "notification" that links me to a spreadsheet, but the actual spreadsheet itself. I originally thought this was what Google Wave intended to be. You could send a regular email OR a "wave" and both would appear in your gmail inbox. It unfortunately ended up being more of a second inbox, with gmail notifications.
