Do you use a Google mail account? Then add your account into your Mail application and have no more need to manage your mails via the webmail interface. The webmailer indeed is quick and easy to use, but I like having my mails all together and searchable on my computer.
Take the following settings, to enable it:
Incoming mail server: imap.gmail.com
Outgoing mail server: smtp.gmail.comUsername: yourmail@gmail.com
Password: yourpassword
You also may take these settings, even if you own a googlemail.com address.
On OS X’s mail.app you will find an extra area on the left hand pane for your Google mail account.
