I agree with point 1. Alignment is a bit of a pain but using the  
arrow keys moves in small increments.

I've overcome point 2 by the liberal use of \phantom{} so that all  
spacing remains constant. The duplicating the slide, selecting the  
graphic and dragging the version without some phantoms makes the  
additions appear without changing any alignment.

Point 3 is not correct! I can drag the image back to LaTeXiT and re- 
edit the equation; LaTeXiT seems to embed the LaTeX code as a comment  
in the pdf file. Sigh... when LinkBack worked in Keynote 2 you could  
simply double click the equation and it would open in LaTeXiT for  

Good Luck,
