Labels, symbols and arrows
A track on a chart is more use with the times written along it. Legacy Debrief let you label a track's fixes every so often, mark them with its symbol, and put direction arrows along it, each at its own frequency. Debrief now does the same: select one or more tracks, say how often, and the map labels the times on the clock's round numbers, beside each track, thinning them as you zoom out so it never turns into a smudge.
