we have published a new plugin
Detect the current scrolling position of the repeating group. Use case: set a custom state to show only 10 items in your repeating group, once the scrolling positing approaches the end of the repeating group, change the custom state to show 20 items etc. This makes loading of repeating group much faster and smoother.
