I just stumbled upon a video, made by the developer, showing the capabilities of his container plugin which is able to morph between presets in various ways… and many more. Impressive!
It’s a great concept, I’ve played with it some.
Keep in mind you can do something very similar to this using your very own Auto Move scriptlet and widgets mapped to multiple plugin parameters.. all without the need for third party software. 
Hmmm… I actually think that the difference between my little script and the rather “grown up” tool in the video is quite huge. 
Well, you can use that scriptlet to morph between multiple values of plugin parameters, using ranged widgets and widget grouping. You can also just manually morph those parameters with one slider. It ends being a very similar effect as some of what that plugin provides, and its more stable/efficient.
Ooh, this is exactly what I’ve been looking for! Was thinking about doing something to achieve roughly the same end as an extension but this seems to do the job! Will be trying it out for sure.
