If for some reason you have not noticed it yet, the project has been officially abandoned for about two years now. So all development is stopped and I see posting new requests as completely pointless. Of course this project is open source and someone might come with an idea to make an update. However I see it extremely unlikely as no one had ever shown such an interest during the years when the project was active. There are also some technical problems with some outdated dependancies, especially...
