not up to snuff (yet)

With work this could be a powerful tool, but as currently offered it is an early beta at best. Examples: Margins exist only on the right side of objects, margins have a minimum width of 5 pixels, the validator insists on nesting multiple objects for no apparent reason. Once a layout box is created it can not be altered, only deleted. Documentation is nonexistent. As currently offered (v1.3) this is not suitable for any but the most rudimentry of layout tasks.
