Really appreciated the core source. A lot of doubts are gone and can finish a lot of ideas now.
For instance, how to make a minimalist project format with the minimal Sencha Ex.JS dependency possible. A "bare bone" like project. Service format, as far as I tested seem to have some things in it.
I just want the basic server and session management / Ajax handling etc. No lib dependency of any kind. I'm learning the code and seams very feasible.
Thanks for any tips..
