Good, but upgrades changes the style

First the ColorWay theme excited me with many features to build up a website for professional marketing of companies and freelancers. And it is easy to use as a parent theme for child themes with a few design changes.

But with upgrading the theme version the nightmare started: There are upgrades of the theme making the website looking differently. The upgrade overwrites custom CSS settings, drops or renames former CSS classes. Hours of works to rebuild the previous design are necessary. I can not recommend that theme because of the lack of backward compatibility.
