Hi @myter,
The topic comes up from time to time. In fact we even published an own editor at some point, however it is now outdated.
You can also find some people of the community creating their own editors, see for example here and the editors linked on our community page.
I also know of specialized builders which are developed and deployed in-house in the respective communities, sadly those are not open source.
So overall there is definitely interest in having a graphical editor.
