Don't misunderstand. I don't think the core functionality of textFrame should change. I'm just saying your users might use textFrame to convince their users how their product can solve their user's problems by showing them around the app without actually going into the app.
It is really helpful for SaaS that requires a sign up before users can use their app. Since registration is a big wall people wont go over unless they have a good understanding of the product. Most SaaS products try to do this now with images and videos.
So what I was suggesting is basically casting a wider net for textFrame. You currently market it as a tutorial solution. Consider marketing it as a "product show off/Demo" solution. Which would also include tutorials as well has any other way your users might want to show off their product.
When you say marketing tool, what sort of content do you have in mind?
Also, I do provide the ability to embed in your landing pages, the instructions are at the bottom of my landing page.
