When I am building a section with text (or other content) on desktop, I sometimes need to rebuild (create a new section) on mobile, because of a totally different mobile design. So you will have to create two sections, one that is visible on desktop and one that is visible on mobile.
This solution works great, but: when a client is editing content on desktop, this content won't change on the mobile section. Because of the two different sections.
I really hope to be able to 'Get text from' on a static page, so desktop and mobile content will change together when edited. Maybe this can be done with something like: 'Get text from "same class/id?"
