Is it possible to edit the excerpt character length on the Latest News Widget?
You can use following filter/code: http://codex.wordpress.org/Function_Reference/the_excerpt#Control_Excerpt_Length_using_Filters to change the excerpt length. Add the code to functions.php.
Do I have to add it to the functions.php of the theme itself, or create a theme-child. I assume the last option is best for updating the theme without loosing custom functions. Am I right about that?
