Well, what I'm saying above applies entirely to the regular GUI tools. (as in, just editing text like in a word processor) I don't code, so I'm wondering if the GUI tools are really buggy for anyone else.
It's not that the GUI tools are buggy, but rather the GUI tools by themselves are not sufficient to make a quality web page. The GUI tools are not the equivalent of a word processor, which by itself can produce a quality document without looking at the formatting tags.
In my view it's unrealistic to expect that you can make a quality web site or even a web page using only a GUI tool (from whatever vendor). The GUI tools are aids to get started. But while you probably don't need to be "a coder" it is very helpful to have enough of an understanding of HTML to take a peek at the code view and see the formatting tags. By glancing at the tags it's usually evident right away what's happening.
If a person is adamant about not wanting to look at some HTML tags, a different tool such as one of the on-line web builders may be a better choice.
Hope this helps.
