To support animation natively, I think Ur/Web will have to be able to express 
sources over CSS properties and DOM information like the cursor position.  I 
believe that without these sources animation will be difficult.  From looking 
over basis.urs and the Ur Reference Manual, I think that to make an animated 
sliding open window, we would have to have a static CSS file with styles for 
all of the window positions. Also, without access to information like the 
position of the cursor, effects like drawing a new window box beside the 
cursor where the user clicked cannot be expressed.
