I already asked for an (user selectable) layout manager some time
ago. Such a manager would replace or include docking managers, that
essentially control the *layout* of a docksite, while docking itself
is only a minor addition. Then AutoSize should be handled by the
applicable layout manager, and anchor docking will become just
another layout manager. A stable algorithm and protocol (API) has to
be established, that allows all layout managers to work together.
I have been thinking about layout managers. I think that this should
be an add-on
to the currently existing layouting (to preserve delphi
compatibility): I imagine a component that one drops on a form. One
sets the 'target' control (control whose children should be managed)
and some properties.
Depending on the layout one wants, a different component must be dropped:
TLayout
+- TAbsoluteLayout
+- THBoxLayout
+- TVBoxLayout
+- TTableLayout
+- TBorderLayout
...
Each descendent has different properties. Changing the layout just means
dropping another component; something that can be done run-time.

The only thing I am unsure about is whether TControl should be made
TLayout-aware.
IHMO probably not, except for providing the cneeded callbacks/hooks
