With this release, I upped the price by $2.00 (USD). We will see if this causes a stir. If it does, then I'll lower it again, but I think being $3.99 is still a reasonable price. My goal is to get the app to act as much like the console as possible. This means having soft-key support and allowing users to customize how the interface works like one would do on a display. I think this is possible, but it will be a lot of work on my end, which is why I've increased the cost of the app.
