Editing the "Open Tasks" widget in the home page of CRM

Hi, 

I'm trying to find out where i can get information on how to change the "Open Tasks" module on my Home page from just listing 5 tasks to listing all of them in one list where i don't have to click through them 5 at a time. Basically i want to see the same long list that i get in the App which i can just scroll through. Can someone please point me in the direction of where i can find out how to edit it? Thanks in advance :-) 

Brett.
