HTML also has something else - CSS, The object inheritance model in LC 
allows you to inherit properties (e.g. colour, margins, etc.) for your 
objects - but it doesn't have any easy way to classify together  (I 
wanted to say "group" but that would get confusing :-) a number of 
objects. So in the example here, there were a bunch of buttons (<li> 
entries) whose properties could be changed consistently by tweaking the 
CSS. I think we lack an equivalently easy way to do it in LC.

Not too long ago we added "behaviours" which allowed us to define a 
script behaviour and attach it to many objects. I think we could benefit 
from an equivalent  'parentAppearance' which would define the properties 
of the parent, and allow those properties to be inherited by the objects 
which specify that parent (over-riding, or rather adding to,  the 
default inheritance via the object / group / card path).

Maybe it's confusing to refer to this as 'appearance' - maybe it should 
simply be any inheritable property - I don't think those are all 
appearance related.
