Components for building attribute forms based on XAML type component definitions with the addition of some layout containers (i.e. Grid and Stack panel) and additional Text (Label) controls that are not linked to an attribute, it would make creating these forms easier and the rendering in the Web clients would be much better aligned to the Desktop version). As it is now the Web rendition of the form is awful and in need of work.

If these also exposed some basic properties to control their display (font, width, height, padding/margin, Attribute to bind) it would be good also. The properties panel (including associated attribute properties) should be displayed in the form builder, docked to the left- or right-hand side. The panel being populated as controls on the form are selected.
