The KDE community has announced the release of new version 5.21 of the popular Linux desktop interface with lots of new features and bug fixes, this release focuses specifically on improving the look and usability of the Plasma desktop environment.
The first highlight of the KDE 5.21 is the completely new Application Launcher (Kickoff) that enables you to find, reach, and run your apps faster and easier. The new launcher features two panes to make it simple to locate your programs and comes with an improved keyboard, mouse, and touch input, the Support for languages with right-to-left writing (such as Japanese and Arabic) has also improved, and the new Application Launcher included an alphabetical “All Applications” view, a grid view for your favorite tools, and placed all the power actions (“Sleep”, “Restart”, “Shut Down”, etc.) at the bottom of the launcher pop-up so that you can find them more easily. The new app launcher comes with a lot of fixes to the bugs that users report during the Beta testing stage and if you prefer the old Kickoff you can download it from KDE's software store.
Continuing with enhancements to the look and feel, applications using Plasma’s default theme now have a refreshed color scheme and sport a new unified header bar style with a new clean and look, as well as a new theme named 'Breeze Twilight' that is a combination of a dark theme for Plasma and a light theme for applications has been added to the default Plasma selection themes.
The Plasma System Monitor app, is a brand-new app for monitoring system resources, and is now an integral part of the Plasma desktop, and it gives an overview page containing information on important core resources, such as memory, disk space, network, and CPU utilization, and also provides a quick view of the applications consuming the most resources which permits you easily locate and zap applications or processes that are slowing your computer down. The Applications page shows you all the running applications along with detailed statistics and graphs, the Process page is also available for per-process information, and the History page shows the evolution of the use of your machine’s resources over time. Finally, you can also create your own new customized pages using the page editor, this lets you tailor the information you get from your system to your needs.
