looking for a preview window plugin

To add it to an existing dock, you can also use the Add tab menu of the doc (in the menu).  

That doesn't work as desired. I need to zoom independently.
And secondly as rich2005 already wrote: "A Navigation Dock can be fixed above the Gimp main window. Snag is the dimmed display."

Thanks for your suggestions.
As long as there is no plugin or similar i will switch to multi-window mode while editing and pin the preview-window (New View).
