Schmitz Marcel Bresink has released [1]TinkerTool 5.3, a maintenance update for the under-the-hood customization system utility that works around an OS X design issue that caused preference settings to be updated only after a major delay. The release also adds new settings that re-enable the backspace key to navigate backwards in Safari, disable the revised function of the power button to switch to sleep mode (10.9.2 or later only), control the speed of Mission Control animations, and use Notification Center to display information about crashes. Bresink also notes that TinkerTool's internal architecture has been updated to prepare for the latest developments in OS X (but does not specifically address support for OS X Yosemite).
