It is just the default KDE panel set to 34 and enabled the floating panel option, moved the date and time to the center with two spacers around it and changed it to have the date always next to the time. I also added a global menu to the right of the start button and the pager and then put margin separators on each side of the spacers. I haven't ventured into using anything fancy like Polybar yet...
Definitely for sure! The only thing I wish they would add is the ability to have icon zoom for the task-bar and intellihide to be able to mimic a dock and not use something buggy such as Latte Dock 😵💫 and sadly Plank doesn’t play too well with KDE since the desktop widget gets stuck there, at least on my install.
