I personally follow over 250 projects...I know other users who follow many more. As one of the main contributors to the US Civil War projects, I am constantly searching for new projects that have been created. Having to page through the 125 projects I am already following to find the one or two (if any) projects I am not following is quite tedious.
When using the "search projects" box, it would be great to limit the search to either projects I am following, or projects I am not following.
