iGigBook version 1.20 currently waiting for review

This update adds some tweaks to the app so that it can operate correctly in the new multitasking environment of the iPad. Currently working on showing charts two up in landscape mode and easier ways to accommodate individual sheets/packets of music. I'm finding that a number of purchasers do not have any of the books indexed, but want the application to do stuff with their stuff. No problem, the customer is always right.
