I've already been testing it. It seems incredible how well finished it is and how well it works. I like it. Except the icon (ugly). I was looking at the GitHub website and seeing everything in that language that I don't know if it is Chinese or Korean, I was afraid that the app was in that language but it is in correct English.
Thanks again.

Yes the app icon is terrible which belies how good the app actually is. Like I said, it makes updating the config.plist so simplistic, all you need to do is import all your settings with a few clicks on the selection tabs, from your old config.plist to the new one and save, then all that's left to do is insure all your Kexts, SSDT and Drivers files are in the correct folders and you're done.
The great part is, with the builtin OC validate option you can then check for any misplacements that needs correcting.
I am very impressed by it and sent the developer the acknowledgement. The only drawback is the app it self is not automatically updated or with builtin update notification, you need to periodically check for updates and down loads on GitHub, but I think that is something the developer will apply as the app evolves.
Happy you liked the recommendation.
