Not really a big problem, but I couldn’t find such information on forums, so here we go…
Does anyone know why antergos (KDE) Package Manager doesn’t “inherit” system themes and uses its own interface? In other words, I use KDE Breeze (Dark) theme and custom window decorations. So ALL apps look like this - https://i.postimg.cc/cLsgCwQ0/kde-apps.png
However, no matter which theme and window decoration I choose, Package Manager always looks this - https://i.postimg.cc/8cND4BkC/package-manager.png (see how minimize/maximize/close buttons are totally different).
Why is that? It happens on 3 computers (all running antergos KDE), no matter which theme and window style is used on system.
