How to modify existing widgets?

Hello,

I need to make the Home page more useful to my techs by changing or creating a new widget to show their tasks/requests. 

For example:

My Tasks, seems to only show tasks that are assigned to the technician, but i want to modify this so it will also show tasks assigned to any of their groups. 

My summary, I would like to modify this so it shows Active Requests assigned to the technician or their groups.

My approvals, this does not seem to show approvals for Solution articles.  Is there a way to make it so Solution approvals show here as well?

How can i go about doing this?
