The "Tiling2" branch of Enlightenment has now been merged into core, which provides major tiling improvements to the window manager.
Tiling2 is a major advancement of Enlightenment's tiling module worked on by several developers and is much more stable, tiling is now done in a tree so tiling can be done however the user is like, and there's good support for floating windows.
Tiling2 is considered a significant to Enlightenment E19 core and has no known regressions and will serve as a complete replacement of "Tiling1" to serve full-time for tiling window needs. As of Friday, Tiling2 was merged to master
Those wishing to learn more about Tiling2's features, shortcomings, how-tos, and other information, can find extensive information on this new module in Enlightenment core on the Enlightenment.org Phab
This is another great addition for E19, which will likely be released later in 2014, and already features a huge compositor rewrite
, improved Wayland support
, and many other changes
over Enlightenment E18 that was released near the end of 2013.
