I am wondering if there is an extension or some possible way to have two tabs open in one safari window at the same time? For example: I use Safari in full screen view most of the time (lion), but I have a 27" iMac and it stretches the pages across the entire screen. I know that I can resize the viewing area within the tab but I would like to be able to have two tabs viewable at once within the same full screen window. Is this possible? Thanks.
