In other web site development tools, it is pretty standard and highly useful to be able to support multiple pop-ups in a web page. Adding the ability to have pop-ups treated like objects which can be targeted by specific controls adds a lot of functionality that is missing currently.
For example. I would like the ability to have a separate pop-up for each image on a home page to provide informational context to the user dynamically and allow them to click on a button to follow that path. So, if I offer multiple products, they can see a preview of the description and click to go to that page within the pop-up.
Additionally, I would like the ability to use a Website URL call to open a page and the pop-up on that page since we currently do not have multiple page pop-up functionality. Having a button in the Global Header which is set to "Open Pop-up" is useless when the current page does not have that pop-up or it has a different pop-up and it doesn't make sense for the button to open that pop-up, or the page needs a different pop-up. Having only one pop-up per page is very limiting.
