Added checkbox option to reverse delay direction. New default direction is the reverse. This new option needs to be ticked to achieve old delay behavior prior to this release.
Changed presets system so presets persist after extension is updated or deleted
Changed parameter ranges for easier animating. Offset control now has a range of -1000 to 1000 instead of -100 to 100 for example.
Starting with this version, releases will now be built with blender --command extension build
