Thoughts on Blue Cat Audio 'Plug N' Script'?

Has anyone used it?

Is it a good first step into plugin making? or will it mostly be irrelevant to learning better code base? ie, don’t start on Snowboard if you want to learn how to Ski.

I have some limited experience with it, but I intend to do more with it. Its quite nice for prototyping ideas quickly. Once nice thing about it is that you don’t need a Steinberg license to make and distribute Plug N Script scripts…
