Unsanity today released maintenance updates for two of its popular Mac OS X enhancement utilities. Tweaks, bug fixes, and minor enhancements have been added to ShapeShifter 2.0.1, the customization software that allows users to change the overall appearance of their Mac using themes, and WindowShade X 3.5.1, the utility that brings the familiar window-collapsing effect from Classic Mac OS into Mac OS X, and allows users to control window shadow settings.
