Gmail reveals the “Delete Button”

I’m an early adopter of Gmail, and stay tuned with the latest improvements of Google’s web mail (first appearing on the English display language).
The delete function was only available in the menu for the time being. It was apparently possible to create a button with GreaseMonkey, what did Rodrigo last September (haven’t tested it personally).
The Delete Button is now available, and even if it could be considered as a “gadget”  for the following reasons :

•  with Gmail don’t need to order your mails any more”, first true principle
• the anti-spam engine is rather efficent, not bothered with spam any longer.

it is really useful.

I’m waiting for :

• a WYSIWYG+view HTML editor , so i can prepare my posts on-line in Gmail (advantages : user-friendly English check spelling+backup)
• a Contact manager with much more advanced features
• a integrated calendar

Next step : “Ctr+Alt+Del” button  in the GoogOS ?
