For the paranoid or detail obsessed, Grouped Access Tools (GAT) would be a welcome Task Manager replacement. It also would appear to be a valuable software debugging tool. The interface is aesthetically spare, but not inappropriately so, as it provides well structured information on first launch. The menus seem logically arranged, and context menus are provided.
Installation is straightforward, but there's no option to exclude or specify the location of the Start Menu folder. GAT appears to deliver on all its promises, though the Memory Editor option never became an active option and couldn't be tested. With no Help file, excepting the brief Read Me file, you will have to discover the purpose of some features on your own. The "Command Pancrav" (whatever that means) didn't make much sense, but there is a list of available commands in the Read Me. This program would definitely benefit from a Help file, complete with usage examples.
GAT never crashed during testing, and is quick and responsive. It is freeware, with no limitations, but there is a donation link in the help menu. Uninstall was easy, but it did leave files behind in the install directory. Overall, this would be a fantastic Task Manager replacement, and as a debugging tool it has promise. A little more clarity (and a healthy Help file) would illuminate some of the esoteric but potentially powerful tools. Recommended for developers and system tamers, but not the average user.
