Hello
Okay, I hear what you're saying. I'm disappointed, though, because I've been buying your themes and extensions for different projects for a long time now, and I felt more supported.
If I understand correctly, I need to start by creating a new location in the layout (cf Step 5 of your document?)
I'm a bit surprised that you're talking about helix ultimate, which is why I was wondering if some of your paid themes didn't already have other slots corresponding to the template of the old site.
That's what's motivating me to buy your templates, otherwise I'd just use helix Ultimate!
Regards
