Hi, Some questions/remarks about math fences 1. When using \definemathfence[colorbracket][bar][middle=0x7C,color=red, command=yes] \starttext \startformula \colorbracket{\frac {a}{b}\fence a = b}^n \stopformula \stoptext The delimiter is of the wrong color (black instead of red), and the clause after \fence is red. I am doing something wrong or is it a bug. 2. For some types of expressions, for example, probability, the middle delimiter should have the space similar to mathrel, rather than mathord. For example, while typing I often use: \Pr\left( X = \frac {a}{b} \,\middle|\, Y = \frac{c}{d} \right) Would it be worthwhile to add these extra spaces by default (not sure what is the convention in physics/quantum mechanics for bra and ket notation) or as an option. 3. Finally, why are the default values of left, middle, and right = 0x2E. Isn't 0x7C a better default? Thanks, Aditya
