I don't mean to meddle in. But, IMO, just don't use OpenCore Configurator for one to two weeks after a new OpenCore release. Or don't use it at all.
Use something that is reported to be good by the majority.
I use Plist editor Pro or Smultron. But, I'm also a blind user, so it is much easier to use those tools over OC Configurator. It is not difficult to use Xcode plist editor, or Smultron etc. As long as you refer to the OC manual.
Don't take me wrong, the concept with these configurators is awesome, and it is good to let people do things easy, I guess. *click* and you're done with your config. But wait 1 or 2 weeks, especially if OC version got more functionality changes than the previous OC version. That is my opinion.
