Currently, in LabVIEW you can right click a VI's icon at the top right of the front panel to find all instances including where the VI is referenced in a static reference node. Also, when you use have a "Open FPGA VI Reference" in "build specification" or "VI" mode, you can double click the node to open the referenced block diagram. Once the FPGA front panel is open, there's no easy way to get back up to the caller. It would be cool if we could extend the right-click-find-all functionality so that when you right clicked a top level FPGA VI, it would search where that VI was referenced in any "Open FPGA VI Reference" nodes. Currently, when you right click and search, it just says no instances found.
