Thanks for sharing your plugin, dwieeb! I had originally been misguided and realized that my posting on "one and done" when clicking was a mistake within my theme -- and not the first by this theme, which is why I'll probably switch to Catalyst.
I highly recommend this plugin if you want something flexible (you can have it in any area of your site -- just adjust your settings; simple! And it has a modernized look to it, being semi-transparent; you can use one of the semi-transparent images he provides, or you have an option to use your own.
Thanks again for your time in developing this and sharing it with the WP community!
