... and, I presume, the problem to be solved is how to return to the plant overview in the same position you departed from.
Possible alternatives:
- Open the machine view in a modal popup.
- Open the machine view in a new browser tab. The problem with this is that there is no way to close the tab with a button on the view. See Closing browser window from button in perspective? - #6 by PGriffith.
- Add an embedded view into each of the embedded machine views. Toggle the visibility of this when the machine is selected. (To avoid a performance hit you may need to disable updates on all the collapsed views somehow.)
