+Beautiful; one of the most complete look-and-feel themes available for KDE.
Only con is that to get the whole experience (i.e. icons, and the app widgets stylised), you have to install those stuff from the Github page (installing from the KDE store isn't enough). In other words, you may as well follow the installation directions directly from the Github page rather than installing from the KDE store.
It's a little inconvenient, but once you get it working, it all looks great.
Global Themes in Plasma are Meta- or Super-Themes, capable of changing multiple aspects of the desktop environment at once, like Window Decoration, Plasma Theme, Color Scheme, Icon Theme etc. In addition, one can define the complete Layout, like what panel to use where, the menu type used and much more.
