I have been largely happy with the services of Gmail and have not felt the need to look any further for a better email service. However, there are a couple of additional features I still wish were available to me.

1. Adding notes to emails – I would love to have a feature to add my notes to certain emails, something similar to the stickies for paper documents. There are times when I feel the need to jot down something along with an email, and while the organization of emails in the form of conversations in Gmail allows me to do this by replying to myself with the note on the email, I think the ability to save notes is a cleaner (and prettier) way to go about it.
2. Snooze a message - At times, there are unread emails in my mail box which don’t need to be attended to immediately, but are not to be ignored. I don’t like to keep unread emails in my mail box and I fear that I’ll forget about the email if I archive it or just mark it as read. Ability to snooze a message for a day and making it pop up again as an unread email the next day would be a nice to have for me. 

Got any demands of your own?
