New look for the workbench
The default appearance of the platform user interface has been refreshed. The main goals of this update were to adopt a
more modern visual style, reduce clutter, and use whitespace rather than extra keylines to separate user interface
elements. Tabs and part stacks have been redesigned to reduce emphasis on non-selected tabs and stacks.

Global search bar
The workbench now has a global search field in the tool bar. This provides a visible affordance for the "Quick Access"
feature, and may be used in the future to combine other kinds of searches into a single location.
