Added a lot about EWMH.

Removed stuff already done.

Changed "physical screen" and all "screen" that refers to monitors to
"monitor". Slightly less confusing.

-* When hiding a window always set XCB_ICCCM_SIZE_HINT_US_POSITION so
-  the window will be mapped where it was when it was unmapped.
+* IconicState
+
+  Currently we set IconicState only on windows we hide and not when we
+  unmap them to switch to another desktop. ICCCM and EWMH says we
+  should set IconicState in both situations.
+
+  We should also set _NET_WM_STATE_HIDDEN when hiding windows.
+
+  hidden.c should list windows with _NET_WM_STATE_HIDDEN and,
+  optionally, all with IconicState.
+
+* When hiding a window we want it to re-appear in the same position.
+  How?
+
+  Setting XCB_ICCCM_SIZE_HINT_US_POSITION before hiding would work
+  without adding more code, but does ICCCM allow that?

 * Bug: Ignore other modifiers, such as NumLock and CapsLock.
 
-* Use the new xcb-ewmh for the EWMH hints.
+  We can use something like this to find the modifier mask for
+  NumLock:
+
+  xcb_keycode_t *num_lock;
+  num_lock = xcb_key_symbols_get_keycode(symbols, XK_Num_Lock);
+
+  and get an array of keycodes finished by XCB_NO_SYMBOL.
+
+  then compare the keycodes in the array with the keycodes all the
+  modifier masks give. See getmodkeys().
+
+* Extended Window Manager Hints (EWMH)
+
+  - Use the new xcb-ewmh for the EWMH hints.
+
+  I suggest listing least these in _NET_SUPPORTED (* marks
+  implemented):
+
+     _NET_NUMBER_OF_DESKTOPS, _NET_WM_DESKTOP*, _NET_CURRENT_DESKTOP,
+     _NET_WM_STATE, _NET_WM_STATE_STICKY,
+     _NET_WM_STATE_MAXIMIZED_VERT, _NET_WM_STATE_HIDDEN,
+     _NET_WM_STATE_FULLSCREEN, _NET_ACTIVE_WINDOW
+
+  _NET_NUMBER_OF_DESKTOPS can be set to the constant WORKSPACES.
+
+  _NET_CURRENT_DESKTOP is just curws. Set the hint when starting and
+  when changing workspaces.
+
+  We *may* want to support a message to the root window that *sets*
+  _NET_CURRENT_DESKTOP and then switch to it.
+
+  We might want to support _NET_WM_WINDOW_TYPE_DESKTOP as well.
 
 * Bug: We grab MODKEY all the time! We can grab it only when we start
   tabbing instead and release it when tabbing is complete.
