Thanks for bringing this issue up momoz. There are a number of ways we are making our voice reach Apple. We have done so for many years, reasons why Apple aren't so enthusiastic in improving Arabic support in its application is not clear to us.
One main avenue in making our voice reach is to write in this forum - in English - so that Apple staff can understand us, secondly is to keep in touch with Apple IMC and partner with them whenever possible to push Arabic issue together.
ثم مع الاسف موقعنا لايدعم جميع مزايا العربي ولكن إن احببت فباستطاعتك ان تكتب في منتدى العربية هذا مااحببت، وياهلا بك
