That's just dconf lol. It sounds great in theory -- after all, isn't bringing standardization to a chaotic battlefield of different formats a good thing? But in practice it's absolute garbage. I would much rather just edit a config file. Heck, even if you program uses some obscure config format like xml or something language-specific like .lua or .py, I would much rather take a few minutes to learn the specifics of your format than fuck around with dconf. Fuck dconf.
