Resize Safari Windows While in Full Screen Mode
Like using Safari in Lion‘s full-screen mode? You can resize the viewing pane of a full-screened Safari window by dragging the cursor to the far left or right edges, grabbing, and pulling in. This lets you reduce the white space and width of browser windows while still retaining the full screen view.
This is a helpful little trick for web developers with a full window open on one screen while coding in another, or if you want to hide those obnoxious background take-over ads that are popular on gaming websites and IMDB, amongst others.
Thanks for sending in the tip Ashley!
