 By default the plugin will automatically open ILS windows based on the active arrival runways. It's also possible to open windows manually using `.ils <title>` (where `<title>` refers to the `"title"` in the configuration file).
 
 > [!NOTE]
-> **Limitation**: This plugin uses the altitude reported by the pilot clients. Depending on the pilot's weather settings and the flight simulator they are using, the height displayed in the ILS Window may not match what the pilot sees ([more info](https://forums.flightsimulator.com/t/vatsim-ivao-pilotedge-users-be-aware-of-an-important-bug/426142)).
+> The plugin applies cold temperature correction to improve aircraft height accuracy. This is necessary for newer flight simulators with advanced atmospheric models ([more info](https://forums.flightsimulator.com/t/vatsim-ivao-pilotedge-users-be-aware-of-an-important-bug/426142)). For pilots using older simulators or custom weather settings, the displayed height may be slightly different from what is shown in the simulator.
 
 ## Configuration
 
 The plugin reads the JSON configuration file when the plugin is loaded. For detailed configuration options, refer to [the sample configuration file](/Sample%20config). Worth noticing:
 
 - `localizerCourse` must be the **true** heading in degrees
 - `maxOffsetLeft` and `maxOffsetRight` is used to specify the maximum visible range (in nautical miles) left and right of the localizer. Most relevant for airports with paralell approaches.
+- `windowStyle` must be `"CDE"` (Common Desktop Environment) or `"X11"` (X Window System).
+- `defaultTagMode` must be set to `"squawk"` (shows only the SSR code) or `"callsign"`.
