    * Hide content of windows
    * Double click action
    * Min size to trigger smart placement

===== Implementation =====

Different implementations are possible.
Below are suggestions open for discussion.

==== Detection ====

How should xfwm4 be detected:
  * running instance (detect the current running window manager)
  * xfconf channel presence
  * xfwm4 binary included in PATH

How should xfce4-settings be detected:
  * running instance of xfsettingsd (part of the session)
  * xfconf channel presence
  * xfce4-keyboard-settings and xfce4-appearance-settings present in PATH (or .desktop file)

==== libxfce4kbd ====

xfwm4_shortcut_values in libxfce4kbd-private/xfce-shortcuts-xfwm4.c needs to match xfwm4 src/settings.h KEY enum.
Meaning libxfce4kbd can't be updated independently from xfwm4 in case of a shortcut change. (Appending is possible)

Possible solutions:
  * Accept we can only append (add a comment)
  * Add a mapping table to xfwm4
  * Move the mapping to xfwm4 and solve the xfce4-keyboard-settings in a different way
  * Add the enum to libxfce4kbd and use static linking on the mappings
  * Don't use the enum, use g_intern_string or GQuark


==== Embed xfwm's tabs ====

Use a GtkPlug/GtkSocket setup to embed the specific xfwm tabs into the settings dialogs. It would be similar to how the settings manager embeds processes and keep coupling loose for new shortcut/settings updates.


===== Discussion =====

  * The next logical move seems to be a merge of the xfwm4 and xfwm4-tweaks dialogs, however, this bears a few problems:
    * There'd be 2 tabs with the same title (Focus), they'd either have to be merged or one of them renamed
    * There'd be 8 tabs (or 7, if Focus tabs are merged) in this dialog, which seems a bit hefty
