Not using native widget style (there is a workaround)

GUI doesn't use native Qt widget style (Breeze by default in Plasma) but uses Fusion.

Uninstalling PyQt5 with PIP:

pip3 uninstall PyQt5

and installing PyQt5 with distro packages (tested on Ubuntu/KDE Neon, package name python3-pyqt5) is a workaround for now. See screenshot below:

Just tested the workaround and it worked, will be implemented with Yin-Yang 3.0. Thanks

Since every distro uses different package managers, it is really difficult to use them in the script. Instead, I made a note of that in the installation section of the readme.
