To take full advantage of the large canvas iPad offers, core elements of the iPadOS experience have been redesigned and streamlined. So you can get more done, more easily than ever. Today view widgets have been redesigned to show you more information right from the home screen. You can choose among different sizes or add a smart stack of widgets, which uses on-device intelligence to show the right widget at the right time in your day. New enhancements like sidebars and pull-down menus let you quickly and easily access more app functions from a single location, without switching views. A more compact search design lets you stay focused on your main task and open apps or search the web with just a tap. And a new as-you-type experience delivers faster, more relevant results. With Scribble, you don’t have to put Apple Pencil away to do other things. You can write by hand in any text field across iPadOS, and your words automatically convert to text.1 Now available in even more languages. -

Chromium OS
Google
Chromium OS is an open-source project that aims to build an operating system that provides a fast, simple, and more secure computing experience for people who spend most of their time on the web. Here you can review the project's design docs, obtain the source code, and contribute. We think of Chromium as a tabbed window manager or shell for the web rather than a browser application. We avoid putting things into our UI in the same way you would hope that Apple and Microsoft would avoid putting things into the standard window frames of applications on their operating systems. The tab is our equivalent of a desktop application's title bar; the frame containing the tabs is a convenient mechanism for managing groups of those applications. In future, there may be other tab types that do not host the normal browser toolbar. -

Xfce
Xfce
Xfce is a lightweight desktop environment for UNIX-like operating systems. It aims to be fast and low on system resources, while still being visually appealing and user friendly. In order to make Xfce shine a little more out of the box and to strengthen its visual identity we created new icons for all of our core applications and based them on a shared palette to ensure consistency. We also set some further (implicit) design constraints, loosely following Adwaita's principles. The Settings Manager itself received a visual refresh of its filter box, which can now be hidden permanently. At the same time the search capabilities of the filter box were improved by searching the descriptive 'Comments' part of each dialog's launcher (aka .desktop) file. This new dialog represents a merger between the previously available 'Mime Settings' and the 'Preferred Applications' dialogs. Consolidating both in one place means users have an easier time setting default applications to handle files. -

The Plasma Launcher lets you quickly and easily launch applications, but it can do much more – convenient tasks like bookmarking applications, searching for documents as you type, or navigating to common places help you getting straight to the point. With a history of recently started programs and opened files, you can return to where you left off. It even remembers previously entered search terms so you don’t have to. Plasma is made to stay out of the way as it helps you get things done. But under its light and intuitive surface, it's a powerhouse. So you're free to choose ways of usage right as you need them and when you need them. -

Stateless systems strictly separate the OS configuration, the per-system configuration, and the VT user-data stored on that system. Designed so that the user is able to quickly and easily manage their custom configuration vs. system configuration. Clear Linux OS optimizes across the whole stack: the platform, kernel, math libraries, middleware layers, frameworks, and runtime. Clear Linux OS has an automated tool that is constantly scanning for CVEs, which are patched accordingly. This strict separation between User and System files allows for easier manageability and simplifying customization. -
