Please! Add a preference that lets me turn off the Cmd-W keyboard shortcut to close the current chat. I invariably am trying to close a window in some other app, don't realize HipChat is in the foreground, and close some random chat I had open. I realize i can re-open it with the Re-Open Last Chat menu item, but if I don't notice it until much later that might not always work.

I realize Cmd-W is a long standing Mac OS standard UI feature, but it'd be a great power user option to disable it.
