Hi Berry,

You understand correctly, that's the intended way of composing.

I have not thought seriously about themability but it should be possible
through the use of shared CSS (elm-css).

The CounterList example shows how the counters push data into the parents
through events.

Boxes can exist within boxes. AltMain shows this (it is a box that contains
other boxes)

Please add an issue about Safari in the repository. I'll investigate it
when I get back to a computer (I'm on my mobile now).

Thank you for the feedback!
