What you see is correct. We didn’t set out to make an advanced Device Link creator. The basic option that most people would need is to preserve the K channel. But there are many other very good programs (Link-O-Lator, Alwan) that create device links with all the bells and whistles.
I suppose the idea is that you can drop a long series of transforms into the worksheet to model an existing workflow or to create something new, and we wanted to give you a way to capture that whole effect into a simple device link profile.
That said, we’re always open to new features that people want to see, so feel free to enter a feature request for what you’d like the program to do someday. (Web > Feature Requests)
