Nice work, but could use an update

I think there is a need to change this:

add_options_page('301 Redirects', '301 Redirects', 10, '301options', array($this,'options_page'));

To this:

add_options_page('301 Redirects', '301 Redirects', 'manage_options', '301options', array($this,'options_page'));

Thanks for this plugin though, it is still working even though it has not been updated. I would have given it a higher rating if it was maintained.
