Right now, I would like a easy editor that allows me to not worry about HTML4 syntax, and simply adjust the rendered text, while I can see the HTML source code.

The reason I need something like this is that I sometimes do make note() in G’MIC which looks like this:

#@gui:_=separator(),_=note("<center><b>- Additional Information -</b></center>")

See that inside note(“”)? That’s HTML4. And while I can do without a editor, I feel that it would be better to use an actual editor where I can copy and paste.

My code can look something like this (Without wrap lines):
