Here's an "issue". When Retina Mode is enabled, it resizes the stoplight buttons (close/maximize/restore/minimize) to be slightly smaller than they should be. By default unless the size changes (either below or above 100%) those stoplight buttons shouldn't be resized when Retina Mode is enabled, if possible. Right now I have to change the size to 110% in an effort to try to bring those buttons back to their intended size.
