Today the KDE Community is announcing a new najor release of Plasma 6.0, and Gear 24.02. KDE Plasma is a modern, feature-rich desktop environment for Linux-based operating systems. Known for its sleek design, customizable interface, and extensive set of applications, it is also open source, devoid of ads, and makes protecting your privacy and personal data a priority.
With Plasma 6, the technology stack has undergone two major upgrades: a transition to the latest version of the application framework, Qt 6, and a migration to the modern Linux graphics platform, Wayland. They will continue providing support for the legacy X11 session for users who prefer to stick with it for now. The new version brings the new windows and desktop overview, improved colour management, a cleaner theme, more effects, better overall performance, and much more.
I think this just comes down to differences between people, 3x3 grid is far more confusing for me than finding my place in line. Instant desktop change is also super jarring, but if it works for you then keep on doing your thing.
