Node Indicator
The node indicator is an area displayed between the View’s left boundary and nodes. Nodes divide this area into cells that indicate the focused and selected state of corresponding nodes. Indicator cells at the intersection of the band and column header panels provide space for the Quick Band Customization button and Quick Column Customization button.
Indicator cells allow end-users to:
Focus nodes.
Move nodes within their nesting level.
