Adding features to a software product takes time. Show me a software company, and I'll show you a Product Manager in that company that manages a want list of features to add. They can't add them all at the same time. The features have to be prioritized while taking many different issues into consideration. Been there, done that.
With almost 20 years software industry experience under my belt I can promise you that if you had every possible feature you could think of, successfully and reliably incorporated into your product, there would still be people asking you why you haven't added feature X, Y and Z.
Foreflight is a QUALITY software product, with QUALITY support behind it. I would suggest that any feature you would like to see added to the product, simply send them a respectful email asking for it. They need these kinds of requests in order to know what their customers want. Unfortunately, most software product customers would rather complain about a particular feature not being incorporated, than to let the company know what they would like to see. Just human nature I suppose.
