v1.9.3 - Graph toolbar at top of 3D viewer
See CHANGELOG.md for the full list of changes. The graph toolbar (Node / -Node / Nodes / Links / Total Nodes / Total Links / Reset) is now created before the modelViewer and added to rightLayout between the view-mode row and the modelViewer, so the buttons sit on top of the 3D rendering surface - matching the layout pattern used by the IFF media bar and the image editor toolbar. All 57 tests pass.
