It would be great to have a widget that could act as an app creator for a website– so we could have an “install app” button for customers of the website to click on and add a shortcut to their phone of the mobile or specially designed page version of the website– so it could act like the website had an app that can be installed.
Hi there and welcome to the Community, @Lauren_de_Jong 
You see, we create widgets that enhance website engagement and interactivity, but the ability to create full app-like functionality and shortcuts goes beyond our general concep. Thus, unfortunately, we won’t be able to implement this idea.
I hope this explains things.
Anyway, thanks a lot for sharing your thoughts with us. If you have more suggestions in mind, feel free to share them. We’ll be happy to discuss them with you
