Make it possible to edit your style for different elements within the product page itself. So that your styles can't be !important with the author's styles. In other words (I want to make my own page style, but I can't set any elements in the available editable field. For example, I can't set my margin, padding, color, etc. It is very difficult to do this, since the editor changes something all the time and redoes it himself.
For example, if you add a picture and then a second one, then he will add his own after saving the code.
