Applications supporting plugins

This page is a list of GNU projects for which you can write plugins (also called "modules", "extensions", or "add-ons"). The aim is to provide suggestions for members of the GNU Generation project. Rather than trying to be a complete list, this list aims to highlight applications which are fun to work with and practical for new programmers.
