Hi. If it is possible please add option to make unvisited flightmasters red colored.

Ngl, i would also love this feature.

Since there is not API which we can use to detect if a flight master was visited or not, it would be a lot of manual work.

It certainly is possible in some way though.

@BreakBB Some addons like MissingFlightPaths and HandyNotes: NPCs (Classic) can do this. But first one is for Retail, second one has not actual geo data (unlike of Questie which has correct data).
