It would be awesome if paid accounts had the ability to build a PlugOut.
So say i wanted to build a certain type of calculator. Then i would use the PlugOut editor that is editor in a one page only customized for the task type view to build the calculator and once built it would be available in a bubble PlugOut store where the creator could offer it free or for a fee based on the whole idea that plugins are for bubble internally and plugouts are for the world who have a website on a different platform that want that calculator. They would buy it from the bubble plugout store and implement the code into a html element on their website.
In the same way we pay for certain plugins to add cool functions to our bubble pages the world could add ours.
