I started a high-level overview of layouts. ��I first inserted it at the top

do you think?
Yes, another section is better for a start I think.

Here's what I have so far:
**The default behavior**
By default, when a morph is embedded into another morph, the geometries of
the two morphs remain independent.
Let's see this in action...
First, execute the following:
m := Morph new
�� �� �� ��color: Color green;
�� �� �� ��extent: 200 @ 200;
�� �� �� ��position: 300 @ 300;
�� �� �� ��openInWorld.
m addMorph: Morph new openInWorld.
*Owner and submorph positions are linked*
Now, click and drag the green square. ��As you will see, it moves in
lock-step with the blue square that's been added to it. ��If you drag the
blue square, again, the green square moves with it.
*Owner and submorph sizes are still independent*
Bring up halos on either morph and resize it. ��The other morph remains
unchanged while you do this.
We need to explains what are halos and how to bring them up.
��
**Specifying the geometric relationship between an owner and its
submorphs"**
There are two built-in ways to lay out submorphs in their owner:
* proportional layouts - specify a particular area for the submorph to
cover, either:
�� �� �� ��- as a percentage of the owner's total area
�� �� �� ��- with offsets from the owner's edges
�� �� �� ��- a combination of both
* table layouts - organize submorphs either in a row or column within the
owner
OK and thanks for your time :).
