Node detail: a card with a compass rose and the hop chain over the info;
the bar keeps Message / Admin / Add, Ping and Navigate, the rest goes to a
"More" group under the info (favourite toggled in place, delete by a second
tap). Nodes: an arrow by each distance. A trail's height profile in Map
tools and a saved trail's popup. Diagnostics > History: battery, noise,
SNR and traffic charts. Clock > Calendar: today, the weekend and alarm days.
