It should definitely be broken out. That would allow us to have feels
which are consistent with user's expectations on their native platforms,
while still being able to switch between different looks. For example,
standard keyboard binding conventions vary between the Windows world
(where ctrl- is often used) and the Mac world (where the default command
key is the apple or clover key which maps to the Alt key on PC keyboards).
With every major release of their operating systems Microsoft and Apple
do essentially the same: Looks may be changed radically or subtly, but
feel is much more stable and evolves in smaller steps. Apparently people
can more easily adjust to new looks than to new interface behaviors.
Squeak should recognize this observation and provide users with their
expected behaviors where possible.

Other possible feel-dependent behaviors could be:
- text and list selection (Windows vs Rest-of-World)
- mouse button bindings (including the paste via middle mouse button
found in X)
- pop-up menu behavior (I kinda liked the old ST-80 pop up menus with
their selection memory - I'm probably the only one who would admit that...)
- keyboard focus behavior is probably orthogonal to other feel elements,
but belongs into this category, too.

It might be helpful to view a "theme" as a composition of look and feel
elements. That way, we could have predefined "tinymellow", "fruit" and
"kobold" themes (to avoid trademark infringements :-) ) and user-defined
combinations of looks and feels (for example, a secret GNU admirer in a
microsoft workplace might choose a "kobold" look with the "tinymellow"
feel.)
