A little help, if you please

[angelofsith]

For my final year project I'm going to be making an email client for use with Googlemail. It will be very useful and more than a bit awesome. In order to make this as good as possible, I'd like some help.

What features would you want to see in an email client?

So far, I have the fo,lowing:

• basic email functionality (sending, receiving, automatic checking, writing)
• minimising to an icon try icon
• multiple accounts
• alerts when new emails are received
• options to download all email or download them when read
