the TUI mode where the "expanind" nodes are very hard to follow.

of having to expand dozens of things

Generally for tree/graph like data structures a real X GUI provides much
nicer rendering. It'll allow to render the connected lines just as in
the line oriented interface, but in a nicer way using real thin lines
in a tree widget. It'll also genereally allow better text placement
in the window compared to the single centered window in the newt
interface. Also the GUI programs follow the common color scheme of the
rest of the desktop instead of hurting your eye. In addition to that
scrollbars (horizontal / vertical) are a lot more intuitive in a typical
X GUI than in newt.
