I am not a web designer. I have been spending much time here on the editor X platform, both to learn things and build my website, since months.
I have experienced so many unstable situations, or bugs, which many times made me think that If there was someone behind the platform making jokes with me. For instance, on Saturday I finally completed my web template. It worked until today. By the way, I haven't edited anything since Saturday. But when I entered my website today on mobile, I saw that some fonts were not loading and some functionalities not working.
As another example, the "copy element design" functionality is so unstable that sometimes it works when you click on "from this breakpoint", and sometimes on "from all breakpoints". And sometimes neither of them work. Or sometimes I cannot get rid of the "paste element design" functionality until I refresh my page (it doesn't go away when I press the escape key).
This platform is really very exciting for those like me, who are new to web design. But I think, it could be far better and less annoying!
