Elementary OS 6 is now in Early Access Builds. There is still a lot of work to be done before launching a beta version. Here are some features planned for Elementary OS 6:
Updated appearance - from panel and system applications to AppCenter applications. More refined design, thanks to HhandWindow from Libhandy.
Dark style for system components .
Default color chosen by the user for all applications - the color can be changed: Strawberry, Orange, Banana, Lime, Mint, Grape, or Bubblegum.
Major updates to communication and organization applications, based on the Evolution data server.
A major rewrite of Mail - based on Evolution instead of Geary.
New Task Application - manages local tasks as well as any activity lists synchronized with the Evolution data server.
A new installer and initial setup - Installation should be much faster and more efficient, requiring only the essentials.
More multi-touch support for application navigation, using the Libhandy library.
