Send and archive, Quote selected text and Default reply to all graduate from Gmail Labs  

The option to add Send and archive and Default reply to all to compose and reply are now both available by default.  These time-saving features are useful if you often send and then immediately archive or always reply to everyone.

In addition, Quote selected text's graduation means that when you highlight text from an email you want to include in your reply, and then click reply, the compose template will be just what you selected.
