My opinion (maybe I'm wrong) is that wordpress should have something added in its visual editor. And that is something most similar to Aqua Page Builder. So that people can use it, and of course that should be optional to use. So that people can visually scale their own grids.
For example: If theme doesn't have something like it you could use the default wordpress functionality. But most of the themes use shortcodes for that similar to [row] and [one_third] which is usually a nightmare to work with in text editor as well as in visual editor.
If you like this idea, please support it.
Thank you all for your time!
All the best!
