first install these dependencies with:
sudo pacman -S gcc extra-cmake-modules plasma-framework gettext kdecoration
next remove whatever panel you have and right click and select
Add Panel → Application menu bar
you’ll need a few widgets to add on the application menu bar you just created,
they will be :
Window title
Global Menu
Application Launcher
System Tray
Window Buttons
Lock/Logout
Digital Clock
Most of these are already included in KDE’s widget menu, but you’ll have to install the rest.
Namely, windows title and buttons.
git clone GitHub - psifidotos/applet-window-title: Plasma 5 applet that shows the application title and icon for active window
cd applet-window-title
sudo sh install.sh
cd …
git clone GitHub - psifidotos/applet-window-buttons: Plasma 5 applet in order to show window buttons in your panels
cd applet-window-buttons
sudo sh install.sh
then right click on the application menu bar and add the widgets in the order
Application Launcher, Windows button, Window title, Global Menu, system tray, lock/logout
and add a spacer between global menu and system tray.
For the icons, you need Beauty Line which is available in icon shop, and for the overall theme use Sweet KDE again available from theme shop.
From the wallpaper changing menu click on install new plugins and download Inactive Blur
