[Plugin: Blog-in-Blog] Loading animation

I use Blog in Blog for my website, on a single page.
The plugin shows a lot of articles, so it can be very slow to load.

So, I thought to install a sort of loader on the page : I want the plugin to load only few article, maybe 4 by 4 each time I reach the bottom of the page.

A lot of blog can do that but is it possible to adapt this technic to Blog-in-Blog ?

Thank you
