Today I cleaned up and simplified the fraction in mathed.This way I also added support for the optional argument of \cfrac. The LaTeX part and the metrics/drawing works so, but I am unable to set the cursor correctly. Therefore it is currently not possible to set the cursor to the cell of the optional argument. Can anybody please help me with this cursor handling code to fix this?
To see what I mean, enter in a formula in trunk the command \cfracthree. thanks in advance and regards Uwe
