Lack of screen support is stopping me purchasing

When using the program on my Mac I find it to be a great piece of software, but the one thing that’s stopping me buying it is the lack of screen support (I have a Denon Prime 4). I don’t know if it is a cost issue for Algoriddim, but you would make lots more money from selling your software if screens were supported in the same way as VDJ and Serato. Is there a reason why there is still no screen support after 4 years of this controller being released? VDJ have had screen support for ages.

Any updates on this?
