I'm sorry, nothing beats KDL in terms of readability and friendliness. I've been using it in personal projects for a while, and it is just so pleasant. I wish it saw way more widespread usage.
Similar to HCL which is way safer and clearer IMHO than all indent based craziness. Its lovely to see default values loaded thanks to some extra spaces. Brackets for the win!
You caveman! Everybody knew that watching config though a 30*80 chars ssh display in black/white should be enough for everybody.
Who needs help displays, validation or even sliders?!
