The Tweak Tree comprises the left-hand side of the WinGuides Tweak Manager interface. Similar to the Windows Explorer interface, nodes within the Tweak Tree can be expanded by clicking on the áplus sign next to the Tweak Category.
Expanding a node within the Tweak Tree will sometimes reveal sub-categories of Tweaks which can be further expanded.
Ultimately, though, the Tweak Tree will reveal those Tweaks associated with the specific sub-categories. To highlight, configure, and apply a Tweak, simply click on its name to open it in the Tweak Window.
