GitHub has introduced a new feature that allows users to easily bookmark Gists by using a 'star' button, which can be applied to any Gist, including their own. This feature eliminates the need to fork a Gist just to remember it. Users can access all their bookmarked Gists through a dedicated "Starred Gists" link, enhancing the ease of organizing and retrieving important Gists. The announcement of this feature was made by Scott Chacon.
