great! thanks for the explanations.
another two more things I would like to implement while writting my "design
with Edje" and "development with Edje" books:
1. Group inheritance that allows you to override one or more parts.
2. Group A has part B of type GROUP that swallows group C:.
a) Programs in A beign able to STATE_SET on part of C.
b) Singals from A echoing in C.
hard? easy? already in the works? :)
Thanks!
