Hi Kaveh

We are aware that this feature is important for our clients. Please note that most of the controls support a RightToLeft layout. The Form is maybe the last control that has no such support. But you have options here as well. For example, you can use the standard form with our controls inside it. Or manually change the location of the controls. 

This feature has gained some votes and will be implemented in a future release, however, at this point, I cannot say when exactly.

Regards,
Dimitar
