Not being able to structure text the way you want or are used in a word processor is a frustrating, especially for non-techies. Indenting is standard formatting today, and viewing the source or comparing versions becomes almost unintelligible with dozens of special HTML spaces characters   .

Since there is no way to indent regular text, perhaps an easy solution would be to have a "structured indent", by simply using an "none" list-style-type. It would look like this:

ul

{ list-style-type: none; }

quick reference: http://www.htmldog.com/reference/cssproperties/list-style-type/

This would enable people to create nicely formatted indentations like in word processors. Ideally, the Rich Text Editor would include a button for this. More ideally, a window would pop up and you can select the list-style-type (upper-roman, lower-greek, circle, disc, none...).

The above would be great even if a generic "Indent" is added using css — tab1

{margin-left:20px;}

tab2

{margin-left:40px}
