Great Product, Scummy Pricing

I really enjoy this product for what it does. It is really useful and easy to create a score of music on your iPad and be able to export print and use this, especially as a middle school music teacher for arranging music for my choirs. The core product works well, is fairly intuitive to use and has overall been a creative boon. Unfortunately I was incredibly disappointed by the decision to charge 40 dollars for the photoscore plugin for the app. When I pay money for an app on the store, especially shelling out the initial price for this app, to me there is an implicit expectation that if there are any significant upgrades that they should come for free, or alternatively for much much cheaper.

Practices like this where you get nickel and dimed for every new upgrade cause customers to feel inherently distrustful of the publisher. Will there be a new version of the app that we will have to buy in order to get all of the new version of the app?

Perhaps I am being unreasonable, but the price seems excessive in a tablet world.

tldr;
App is 5 stars top notch for mobile composing
App is -1 stars for making me feel like Im getting a good value.
