Updated version to 1.4.5. Updated README with explanation of requirements for overriding queryset() on inline models. Added extra models to sample project to demonstrate sortable models with custom querysets. Improved JavaScript of sortables to be more efficient with better comparison checking. Fixed highlighting of stacked inlines on sort finish.
