Hide aircraft labels in X-Plane
Inside X-Plane open the Plugins menu, select xswiftbus and in there you'll find an option to toggle aircraft labels.
This setting is not permanent! When you close X-Plane it will revert to its original setting. To change this permanently follow the instructions of the next paragraph.
To permanently save label-settings you need to use swiftGUI.
Settings and then select
[...] (at the right side of the X-Plane-line) will open the X-Plane plugin settings window.
Changes to these settings will take effect immediately and are saved through a prompt when you close swiftGUI.
