This is a very useful plugin, and thanks for writing it.
However it's filling up my debug.log with these messages:
[11-Sep-2012 01:46:02 UTC] PHP Notice: get_settings is
deprecated since version 2.1! Use get_option()
instead. in /home/domain/public_html/wp-includes/functions.php on
[11-Sep-2012 01:46:02 UTC] PHP Notice: Undefined index: HTTPS in
redirects/wp-simple-301-redirects.php on line 143
Hope you can fix this in the next update.
Keep up the good work!
