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):

Ah right. Center still works with html5 though even if it technically isn't in the spec. No browser is everything going to remove support for that.
Anyway I'm not sure you'll get any answers because it isn't at all clear what you're asking for.
You can edit that HTML in Notepad. I'm guessing Notepad isn't what you're looking for, so you need to specify what you want better.
