Hello!
I think maybe the promotion didn’t go very far because I happened to see it here on itch when I clicked on “typing.” Maybe, besides itch and the Windows Store, you should also try Steam. But, I understand the frustration, especially because the writing community tends to focus on the more well-known programs.
And that brings me to the second answer: I personally don’t mind having several programs for different things. But I know many prefer something complete, where you can do both outlining and worldbuilding together. If it has that, I would love it, but if not, it wouldn’t be something that would stop me from continuing to use it. As for the outline, I solved it with “reference notes” that I placed on the side. But again, it’s not something that would make me abandon the program.
Anyway, I am loving the program and using it nonstop.
