Replacement for / theming the "Active apps" widget topic

You know the S4 comes with an "active apps" widget that tells you how many apps are running and when you click it it takes you to a task manager? I would like to customize this a bit so it fits my current launcher theme. I don't really want to try an alternative task manager, I just want a widget that does the same as this one but can be customized more?

Same with the lantern widget.
