The limitation of not being able save unless the App is in the foreground maybe a drawback, but I do not think a serious one. However the author of the package has the right to set the price of the product, but I as the consumer have the right to choose if this is value for me & my dollar. For me $20 is a touch on the high side, for what is a one trick pony. Although I have not downloaded the package I would suspect it may be an apple Scrpit. Shame really, because I and some of my clients could use something like this. I might suggest if the price were lowered, more would be sold to make up for the reduction.$15 still no $10 maybe $5 definately
