Hi Matthew, thanks for sharing the idea and the video! This would definitely make it easier to design right inside the page builder. At the moment you can scale text in a similar way for the Mobile version of a responsive page. The reason we only have this on Mobile and not Desktop is because we use a CSS property to do this that is compatible on all mobile devices, but not all desktop browsers that we support. We do plan on improving our text editing in a big way though, and we’ll definitely take this kind of control into consideration.

Thanks again for chiming in! The videos are a big help with ideas like this…
