The AT&T OPEN LOOK Toolkit, Xt+, is undergoing beta testing of Version 2.0 
and is due to be available in January.  It now has the same UI look as 
Sun's XView OPEN LOOK Toolkit, whereas the earlier Xt+ versions were
based on an older OPEN LOOK Specification.  This new look is quite sleek
and streamlined, IMHO.

Xt+ 2.0 has some interesting new features:

	Gadgets: use the same as widgets, but lower internal overhead

	Flat Widgets: efficient container widgets for managing sub-objects
	of the same class, like CheckBoxes, Nonexclusives, and Exclusives.

	Stub Widget: application-programmable widget.  That is, most of
	the otherwise internal widget hooks are available as application-
	specified resources, such as XtNexpose to chain in Expose event
	handling.

Performance is quite good, up a bit from the 1.x releases.  In particular, 
it is hard to get ahead of sliders and scrollbars.
