Double Grid Mode
Double Grid mode allows you to work with two structures side by side. To enable, click the Double Grid button in the Structure toolbar.
When Double Grid mode is enabled, you can work with both structures at the same time. The Structure toolbar actions and keyboard shortcuts will be applied to whichever panel is in focus (the one highlighted with a thin blue line at the top).
Moving Items Between Panels
You can also drag items between the two structures, or use cut, copy and paste to move or copy items between them.
Hold the Ctrl key (Alt key on Macs) while dragging an item to create a copy in the new structure (without removing it from the original structure).
Resizing the Panels
You can change the size of each panel (giving more space to one of the structures) by the dragging the separating border between the panels.
