I published another concrete5 resource
I've been working with kind of 'boilerplate' package for my last several sites. While still a work in progress, I've published it on github.
The idea is to give you a jumpstart on creating sites without really getting in the way very much. It has several different examples, especially in the controller. So hopefully it's simple to just copy/paste into your own files. I also added a kind of basic 'callout' block, an example of the page -> tools file -> page controller -> package element work flow that seems to permeate every site I do.
I'm going to keep building on it, but I'd love it if others wanted to fork the repo and contribute back to it. I'd love to see tons of block custom templates, more examples of base themes, stuff like that.
