how to put have more things on outline?

I would like to show more items on the outline. Currently it shows a recent list of the latest 20 things. I would like it to show the last 50 or more things. *ALSO* is there a lazy loader code that you know that would load the outline like pinterest? There are two questions here.

Ok, I know how to change the number, but how do I add the lazy loader so the outline shows up as I scroll down instead of having to press the "load more" button?

Exactly what Dolphin site have you seen this on?

I'm not sure that can "copy" Pinterest like that anyway.

The evowall has that lazy loader thingy for the timeline; the developer might could add something similar to the outline but that means nothing can be below the outline on the index page because you would never get to see it.
