LorbyLiveTraffic 1.73 is available as a free download.
The main feature of this version is a TaxiGuide app. You can input your intended taxi route on a simple dialog or a gauge, and LLTX will create a string of lights in the sim, following that route. (the gauge is currently only available in P3D V4, but the dialog works for every sim that LLTX is compatible with). You can choose between big yello flashing lights or small red constantly glowing ones.
This may be useful for all those simmers who don't use the in-sim ATC.
