QR code link to current page
I came across [qrcodetag]_[/qrcodetag] and figured I'd see what it actually did... Turns out, exactly what I wanted - a link to the current page URL. Great that this feature was already included, but please document/promote it better in the next release, so the next person doesn't have to hunt and guess. Just a suggestion and thanks for the plugin!
