I’m testing the latest Qubes-3.2, whonix 14 ws template in the community-testing repo (qubes-template-whonix-ws-14-4.0.1-201807190624) & it seems that a lot of the customisation settings for KDE appearance are missing in System Settings.
The Gnome/GTK settings are there but the KDE ones don’t seem to be there. I previously setup my whonix-13 templates to use the Arc theme for KDE & GTK apps to match my fedora templates & dom0. This provided a modern unified look to the whole OS. What do I have to add to customise KDE themes & font settings?
Also - what version of KDE is whonix 14 using. I tried the virtualbox whonix 14 version & everything seemed like KDE5 with all the customisation settings available - qubes-whonix-14 looks more like KDE4.
