Many thanks for creating this - I'm using it on both of my WordPress sites.
Can I make a suggestion? Would it be possible to give site admins the option of a different font (even Arial)? The font coded into the plugin is definitely distinctive, but it's a display font and not very readable - and this is a case where conveying the message should be job 1.
Thank you again. This was a generous, valuable contribution to the cause of an open Internet.
