Many of my sites display dynamic data titles with links to more detailed infomation. In many cases I don't want them to leave the page so that they also look at other links on the page when the popup has been closed. Advanced Layer Popup does this so effectively and so easily and doesn't load the detailed info until needed.
I have used this popup with dynamic data in several different ways - including showing videos, and displaying automatically generated Google Maps.
It is certainly my favourite extension and a frequent feature of my websites.
