[Plugin: WP Social Blogroll] Show 5/show all toggle?

First of all thanks for a nice plugin!

My blogroll is getting quite long and I wonder if there is any way to have it show only 5 posts (or whatever number) as a default with a show all option at the bottom of the list.

I could only find a Norwegian example right now but at https://meretesmonstermonster.blogspot.com/ you find the blogroll under “min bloggliste” and if you click “vis alle” (show all) at the bottom of this list it goes from showing 5 posts to showing all.
