Paragraph shading with rounded corners
Paragraph shading is very useful, but for some reason clients always seem to want to have rounded corners on boxes/panels :)
If we could have rounded corners that we can define the radius of this would give a lot more flexibility for layout. Paragraph shading works inside table cells too so this would open up a lot of possibilities for table styles.
