thank you. As for the bug (3), for your information: From the menu: Epic Elements > Setting > Epic Module Element Option > Module Image Setting > when I then close the customizer the whole screen gets grey and the customizer disappears. It has happened also in different situations in the customizer.
As for the custom code, fact is that we change the appearance of our magazine on a weekly basis and need to have easy processes according to necessity. This is why we are redesigning our site switching to an Elementor-based design, to streamline the everyday customizations. Adding custom CSS code is not an option. It would make pointless the redesigning we are undertaking.
