Bug Description

Plugins that have some additional settings you can tweak (like 3D Rotate) create a preview image. This preview image creation (what happens if you choose "Update") takes quite long whereas the final image creation (what happens if you choose "Save") is quite fast. I suppose that every time you click on "Update" the full image is being modified and then the preview thumbnail is generated, while when you click on "Save" only the result is saved to the original image or something like this.

I would propose to make it the other way around: When you click "Update" first a thumbnail is generated and after that the plugin is executed to the thumbnail (not to the original image). Only if you click "Save" the plugin is executed to the original image.

Like this the previews would be fast and only the final execution would be slow. It has an advantage if you use the "Update" button at least one time every plugin execution. If you don't use it at all it has no impact because still a preview has to be generated when the plugin dialogue is opend.

Impressively sharp analysis...That's nearly 100% the way it works now.

=> Accepted.

Thanks for your bug report.
