A: Hey Marcus, thanks for your question.
You mean https://wpstackable.com/ right?

We do plan to implement it of course.
In the meantime, if you'd like to give us a try, we require Elementor free, and you are not forced to switch your stackable off.
You can use them both, Elementor for our templates and wpstackable for the rest of your website.

Let me know if this can work!
