Howe to change the 'mode' (to dark) in LO 24.0.2 AppImage?

Hello,

I’m wondering how can I change the mode (Tools->Options-> LibreOffice->View->Appearance-> Mode) to dark in the Appimage of the application?
I know I can extract all modules(items) from the Appimage, perhaps make the modification and build a new Appimage. In which Config file are the settings of LO stored?
Any help is much appreciated.
TIA

PS. My regular version of LO (v6.4.7.2, Linux-Mint) doens’t have this settings.

Why Appimage? Download the Debian package from libreoffice.org and install it like this:

cd Downloads
tar -xzvf libreoffice_24.2.0_Linux_x86-64_deb.tar.gz
cd LibreOffice_24.2.0.3._Linux_x86_deb/DEBS
sudo dpkg -i *.deb

You get a complete installation ready for extensions, macro languages, SDK and with a reasonable level of system integration.

Thanks for replying, but that is not answering my questions related to the change of the mode in the apps.

And to respond to your suggestions, I prefer to try a Appimage stand alone first before I’m installing the full package.
My question remains, where are the settings stored?

I am not certain on how to do exactly what you are asking but this information may be helpful.

The modification would be in the ~/.config/libreoffice/4/user/registrymodifications.xcu file.
I did a early adoption of thems in OooDev.
You can see the source here. Unfortunatally it is not working 100%. LibreOffice made some changes along the way that made this difficult to implement. For example I have not figured out how to accurately detect the current theme since LibreOffice has made changes.

I am not sure about this but:
Maybe you could capture the changes in registrymodifications.xcu after the theme has been changed by using a Diff editor to find them and then create or add to an exising file in /etc/libreoffice/ directory.

I found: /usr/lib/libreoffice/program/fundamentalrc that contains

CONFIGURATION_LAYERS=xcsxcu:file:///etc/libreoffice/registry res:file:///etc/libreoffice/registry dconf:* bundledext:${${BRAND_BASE_DIR}/program/lounorc:BUNDLED_EXTENSIONS_USER}/registry/com.sun.star.comp.deployment.configuration.PackageRegistryBackend/configmgr.ini sharedext:${${BRAND_BASE_DIR}/program/lounorc:SHARED_EXTENSIONS_USER}/registry/com.sun.star.comp.deployment.configuration.PackageRegistryBackend/configmgr.ini userext:${${BRAND_BASE_DIR}/program/lounorc:UNO_USER_PACKAGES_CACHE}/registry/com.sun.star.comp.deployment.configuration.PackageRegistryBackend/configmgr.ini user:!${$BRAND_BASE_DIR/program/bootstraprc:UserInstallation}/user/registrymodifications.xcu

This seems to point to the configuration that are include when LibreOffice starts.

In the Live LibreOffice Python project I copy user setting over when the Codespace is being constructed. See the defaults code.
Basically copy registrymodifications.xcu with theme setting into ~/.config/libreoffice/4/user/registrymodifications.xcu

It is to old. Dark mode came out of experimental in 7.5

As settings usually go to the profile below your $HOME (as @vib already wrote) I wonder if you have two versions of LO sharing the same profile…
