A few tweaks I’d like to see in Google Sidebar:

1. A compose link for Gmail. Displaying the Inbox theoretically makes it so I don’t need to have a browser window/tab open to Gmail. Yet if I want to write a message, I need to bring up Gmail in a tab, and click the compose link.
2. A chime when I get new messages. Every other email program in the history of Earth does this. Give us a checkbox so we can turn it off.
3. Lock width. Full screen windows have the scroll bars on their right edge. With the Google Sidebar docked on the right side of the screen (where I have it), I occasionally click on the edge of Sidebar accidentally. Give me a way to lock it — like the Windows task bar.
