 ### Updating the local QTF
 
+At program start, the current local QTF is initialised from the **QTF** default stored in the active root or operator profile. This is a start value only. It does not change the stored default during operation.

 KST4Contest asks PSTRotator for the current azimuth and operating mode every two seconds. The reported azimuth becomes `actualQTF`.
 
 While PSTRotator integration is enabled, the QTF field in the main window is therefore read-only. It displays the most recent position reported by PSTRotator.

 A received rotator position is therefore more than a displayed value. It changes several functions which depend on the current antenna direction.
 
+Without PSTRotator 1, **Use QTF filter direction as antenna heading** can apply a direction entered in the QTF filter, or selected with one of its compass buttons, to the same `actualQTF`. This also works while **Show only QTF** is switched off. **Reset filters**, switching the filter off and restored filter state do not alter the antenna heading. The transfer is one-way and does not issue a PSTRotator command.

+The option is grouped under **Manual antenna heading** and is enabled by default, including for existing root and operator profiles after updating. Clear it to store a profile-specific opt-out. While PSTRotator 1 is enabled, the checkbox is unavailable and the transfer is temporarily inactive. Its stored state is retained, so disabling PSTRotator 1 restores the previous choice. PSTRotator 2 under SO2R is independent of this rule.

Changes to window sizes and positions, relevant dividers, managed table-column widths and the **Group nearby stations** map setting are also saved automatically after a short delay.

 - Storage location: `~/.praktiKST/preferences.xml` on Linux and macOS and `%USERPROFILE%\.praktiKST\preferences.xml` (or `C:\Users\<Username>\.praktiKST\preferences.xml`) on Windows
 - The automatic layout writer does not copy functional changes which have not yet been confirmed with **Save Settings**.
 - Configuration version 6 adds optional column-width entries below `guiOptions`. Older `preferences.xml` files remain readable. Missing or invalid widths simply cause KST4Contest to calculate useful initial widths again.
 - Configuration version 7 adds `GUIstationMapClusteringEnabled` below `guiOptions`. If the entry is missing or unusable, spatial map clustering remains enabled.
-- Older programme versions ignore the additional XML entries. If an older version rewrites the complete file, column widths and the stored **Group nearby stations** choice may be lost.
+- `GUIstationMapAlwaysOnTop` is an optional layout value below `guiOptions`. If the entry is missing or unusable, the map window uses normal window behaviour and does not remain permanently in front.

 - If you encounter problems: delete the configuration file → KST4Contest will create a new one with default values.
