Personal Capital Plus od Alexander Meng

Customize the Empower Personal Dashboard (also known as Personal Capital) user interface. Allows you to customize the UI with several options:

Hide zero balance accounts, sort accounts by value, condense the accounts list, hide header background graphs, and hide your net worth.

After installing, a new menu option will appear under your named settings dropdown called "Extension". From there you can enable or disable whichever options you like.
