Building on the revolutionary symbolic interface system introduced in Mathematica 6, Mathematica 7 adds several important new interface elements—including deep system-wide support for raster images, support for scrolling panes, support for rounded corners and arbitrary rotations, and further automation of interface building in Manipulate.
- Support for raster images in every aspect of interfaces and controls.
 - Automatic drag and drop of images from external sources.
 - Automatic context-dependent sizing of raster images in notebooks and interfaces.
 - Scrollable panes for viewing large expressions and images. »
 - Support for grids and other presentations of controls in Manipulate. »
 - Control interface element for automatic selection of control types. »
 - Named placeholders for creating instant input templates. »
 - New constructs for creating sets of buttons. »
 - Arbitrary rotation of any interface element. »
 - Rounded corners for frames and other elements of interfaces. »
 - Functions for programmatic opening of arbitrary files and URLs. »
