Great plug-in. Best I've seen in of its type! The only issue I have - and it's a major issue for my website - http://PoetryByJae.co.uk - is that Ctrl+P does not seem to have been disabled. This is why I downloaded your plug-in in the first place, because I was expecting all Ctrl functions (including P) to be disabled.
Most of the poems on my website are offered for visitors to purchase a copy for £1 GBP. But why would the want to pay for a poem, when they could just as easily press Ctrl+P to print a copy for free? Also, if a visitor has a PDF printer driver installed on their PC, then they could just as easily press CTRL+P, "print" (save) to a PDF and then copy & paste the text they want from the resulting PDF file. So, it would be useful if CTRL+P could be disabled to stop this means of copying content.
