You can style all the widgets in a report page now! You can add: a background color to a page, borders to all widgets in a particular page and style a widget from this page (instead of clicking through to the edit page).

Tip: You can select multiple widgets to edit by pressing 'SHIFT' even as they click on widgets. If you'd like to just revert a particular widget to the page's style, there's a handy button for that too!
