Yet another awesome tool - appreciate it!
Suggestion: perhaps some colourized text stating "On Time" vs "Delay" somewhere in / below the flight information?
Or maybe with your code and if it pulls from Flightaware it will automatically populate like that if a delay is posted... ?
I also often like checking inbound aircraft status so a link for that?
Can of course click through Flightaware to find that information though so maybe less links / clutter is better.
