The theme code is semi-minified/unformatted on purpose, so that isn’t an issue. You’re welcome to open up in your favorite editor and format however you like.
Thank you answer.
But i think, this is wrong way (at least for Pro themes). You make life harder for yours customers. I don’t know anyone who use themes as is, and don’t need customization or child themes. But with ugly code styling – this is much more harder, because i need first format code in readable style.
