ObjectiveUI & ObjectiveEvents - securehook to API calls for compatibility with addons that work with the objective tracking interface - let the API hooks invoke ObjectiveUI functions when possible - ObjectiveUI framescript handlers should use the corresponding API call if possible, so that addon space can be fully aware of our actions - Sanity check cached data when possible during 'Remove' hooks ObjectiveInfo - Add cheevID to criteria info ObjectiveCore - Index quest tracker blocks by their watch offset, and use that to verify whether the given block frame should be released into pool ObjectiveFrame - Differentiate between visible and non-visible unused buttons, and only release when their quest has been dropped
