Thanks for your great plugin and all of your skillz (i'm reading your book!)
I know that is not a issue, but like recommended by some best practices, i enable DEBUG on my WP dev version and it fires me some notices from your plugin (version 3.5.3), about deprecated function attribute_escape
So, i found the lines:
$options[$k] = attribute_escape($v);
and replace with the good function esc_attr
I just want to ask you, please, if you can include fixes that avoid notices in next versions of your plugin.
Thank you very much!
