While I have no issue with the app itself, what it does, or how it does it, I do have an issue with the viability of the app or why it was written in the first place, other than for the developers self educational purposes. There are already many paid and free apps available that do this exact thing - and more. Why does the Mac community need another separate app for this that just sets a single value of a parameter file? If an unique app was made for individuality setting each parameter on a Mac then their might be hundreds or even thousands of such apps, The logistics of this would be incredible if not insane. Hopefully the developer will be able to concentrate their efforts on something more encompassing, unique or useful in the future and as such make a more viable contribution.
