* Use global state instead of per-layout - so now window is minimized on
all workspaces (EWMH requires that windows with _NET_WM_STATE_HIDDEN
set should be minimized on any workspace but previously they were not)
* Use `windows` instead of `modify`. That should fix bugs related to
actions that should be done by `windows` and not done by
`modify` (fixes#46)
* Mark module X.H.RestoreMinimized as deprecated
Calling these functions during message handling results in the loss of layout state.
This fixes a number of bugs related to the combination of X.L.Minimize with a decoration.
XMonad.Hooks.Minimize handles both minimize and restore
messages. Handling restore messages was already done in
RestoreMinimized, which this module intends to replace.
Despite myLayouts currently being more popular in examples, make
them all myLayout as in man/xmonad.hs to avoid mixing them in the
same module as was done a few places, leading to confusion for some users.
