Research direction
The issue is that when more gauges than the screen height are added, they are not scrollable. Investigate the termui rendering loop in the main package, specifically how widgets are laid out and drawn. Look at the Grid or Row implementation to see if there is any scrolling mechanism already. The fix likely involves adding a viewport or scroll offset that responds to keyboard or mouse events. Check if there are any closed issues or PRs related to scrolling for guidance.
