Please note that these plugins are written by third parties. We do not have any control over them, and we cannot give any assurances as to how well they perform their advertised functions.
You can write your own plugins too! We don't document this specifically, but you can have a look at the existing plugins for some directions. In general, Administrate tries to abide by Rails's conventions, so that hopefully should help!
