Hi!
Maybe you can add the free version here too as a demo? I think there is an option to upload a file in the same project as demo.
It would be a bit of a hassle since whenever I need to update the plugin, I'd need to update it in multiple locations. >.<
Not to mention, the normal version is not a demo, it's the full version of the program. The Pro version is more like DLC that adds on top of it. So labeling it as a demo here may cause some confusion.
Thanks for the comment though!
