One of the most underrated plugins out there. The weight-based blending and being able to select individual parts from each look for both morphs, hair, skin, clothing, makes all of the appearance presets I have made so much more valuable.
One usability suggestion though - adding a "reset to current" button might be a good idea. I just reload the plugin when I want to do that, but having it in the plugin itself would be a little more intuitive for new users and it'd be a good occasion to bump it back up for more people to discover it :)
