The Part View toolbox provides a hierarchical view of the part. Each setup is listed with each of the feature of the setup listed underneath. From this view you can select, show, hide or modify features. If you click on an item in the list, a triangle appears in the right margin. Click on this to reveal a menu of operations you can perform on the item. You can also reorder features, or temporarily include or exclude features from toolpath generation. The checkbox to the left of each item indicates whether the feature will be included when toolpaths are generated. By removing the check, the feature will be temporarily excluded from the toolpaths. This is a useful feature for debugging your toolpaths.
