sjanssen:
I've merged all the changes from the xmonad-class branch to the core. There are a few changes users and developers ought to be aware of.
Layout state (such as the currently selected layout, nmasters, the master/slave ratio split, etc.) now persists across restarts. Because the old layout-resetting behavior of mod-q is sometimes useful, we've added mod-shift-space to the keybindings to reset layout settings on the current workspace.
Some contributed modules haven't been ported yet: HintedTile Magnifier Mosaic SimpleStacking Spiral SwitchTrans
Feel free to pitch in with the porting effort.
Developers will notice that we've moved from the record of functions approach to a Layout class. So far, this has been a big win, allowing us to write layouts and layout transformers in a more structured fashion. Porting simple layouts to the new system is fairly easy, see the core layouts for examples.
Special thanks to David Roundy and Andrea Rossato for initiating this branch and doing the lion's share of porting to the new system.
A layout class has been a long standing design plan, to help make it even easier to write nice shiny layouts. It's great we've got this in now. -- Don
