In the first instance, just wanted to say - really great piece of software!
My suggestion - It would be really useful if there was some kind of option to print the PLOG off the iPad in some kind of A5 format via Airpint. That way it would fit into most kneeboard setups and the like. Given the limitations of Airprint I imagine this would have to be accomplished in the app itself - basically producing the document itself in landscape and only covering half the page width wise. That way when it prints it would be simple to fold /cut in half and you would have an A5 sized PLOG you could slip straight into your kneeboard.
At the moment the only way of accomplishing this is to export the PLOG file via e-mail or similar and adjust in some other software, so having something in App would be a lot less hassle.
