A little update; I'm working on adding more configuration options and features so people can further customize the posters created, here's a list of recent additions:

• Select the scales and modes to display - I've added boxes from which you can select the scales to display (the format of the posters is still limited to 6 per page but I'm working on automatic resizing if 7, or 8 scales are selected, or if less strings are displayed and there is more space).
  


• Customize the colours used - I've added options for changing the colours displayed on the notes and also the background and fretboard areas. Took me a while to write the javascript colour chooser which I'm quite proud of.
  


• Re-organised the page to be a little easier to use. I'm still working on more changes to make the user experience even better.
  


• after creating a poster you will be given the options to customize.
  

Please leave feedback and comments, I'm going to be working on this more over the weekend and appreciate any feedback and suggestions.
