I have installed RC2 now, but I see no difference in formula editor.

I see no difference. And why should there be a difference? The command 
"binom" takes two operands, so the expression is finished after binom { 
A } { B } and I see no need for brackets around it.

Do you want bug reports for these problems?

I personally use blanks only where it is necessary to separate things. 
In addition I use carriage returns to structure expressions, especially 
matrices.

For example I write
	f%prime(x)=func e^-{x^2 over 2}
and
	6 a + 5,5b
latter because of the bug, that in 6a the a is not italic.

Kind regards
Regina
