Suggest a feature to Gmail

Don't know since when Gmail decided to replace the 'Suggest a feature' link from a 'remote area' to the front page of their Help Center. They also added new features (most likely based on suggestions by users) to the 'most-wanted list'. Here are some interesting items：

• Backgrounds for messages Something like the Google Personalized Homepage?
  
• Animal emoticons I really don't know why animals but not humans
  
• Hierarchy of Label system (i.e. sub-Labels) I would suggest label archiving instead
  
• Ability to block a user from sending mail to your account
  
• Sort messages by size, date, sender, etc. I believe this is the most wanted
• Integration with other Google products such as Calendar, Groups, Reader, Picasa, etc.
• To-do list This should come with Google Calendar
  
• Export messages to a CD for storage Gmail Paper coming true?!
• SMS notifications for incoming messages
• Have Gmail do my laundry Is this a human verification? Or another Google joke?

They also added in a new field called 'Location'. Maybe Google wants to know which where do their picky users come from ;). Vote for your most wanted features (up to five) now!
