And I don't really see what the issue is: are we talking for or against the bidirectional algorithm? or is it for or against your system's typesetting features?
In the first case, then I think the issue is clear: every current Arabic system must be bidi-compliant. In the second case, I would like to know more about your system, so please do not disappear.
I believe there is no issue. We are taking for better bidirectional algorithm. I am not talking for my system, as I said before that is not my system. I will not disappear and will talk more about TeX-e-Parsi;s features.
I just felt that you guys think the current bidirectional algorithm of LuaTeX is fine and have no interest to study other systems.
