Just so some people know... if you don't edit above where you place the Time Search in the index.php, it will show up on the same line... So, here is a better way to describe what to find...
Find:
Code:
makenavoption("Build Mailing List","email.php?action=genlist");
And replace with:
Code:
makenavoption("Build Mailing List","email.php?action=genlist","<br>");
makenavoption("Time Search","time.php?action=modify");
