CM1 needs a widget into which content contributors can enter text without it getting styled. This is important where a contributor may be copying from another web page and the site designer doesn’t want that content to drag over any inline HTML that will break the look of a page.
The Simple Text Widget is currently a poor choice for dealing with copied inline HTML because it has no HTML view like the Rich Text Widget has. Unfortunately, the Rich Text Widget offers too many options for content contributors to likewise add their own styling that is not desired.
A Plain Text Widget would be ideal for minimizing contributor caused markup problems.
