YES, please! I don't understand why the developers refuse to make a childtheme possible. I can't adjust everything about the theme... I want a different sorting of the project within the categories. I want a spinner at lazyloading. I want to be able to enter CSS comfortably and not via the too narrow CSS input. I want to be able to extend the theme without having to rewrite everything after every update. ... this is not nice. The theme is too expensive for that you can (may) do little oneself.
I hope there is an insight.
