The CustomCompareCommandProvider seems to override the entire commands object which conflicts with other addons that add or remove commands to the context menu of items in the list.
For example, the Digizuite addon will not be able to show custom menu item for cropping in the Digizuite widget when CustomCompareCommandProvider is installed. Commenting out the 2 add statements in the CustomCompareCommandProvider.js solves the problem (but I guess disables the comparer).
