It was not so long ago that Plasma 5.18 graced my computer and very excitingly, 5.19 is here now. Since Tumbleweed is my main Linux system I use, I decided to share my experience on openSUSE Tumbleweed but it should be noted that you can enjoy Plasma 5.19 on Leap as well using the backports repositories. Leap is not my preferred method but it is an option.
Bottom Line Up Front: It is another fantastic release with much attention being made to the finer details that enhance the usability experience without taking away from any of its functionality.
