One thing I'm always wondering is how people organize their code in an AngularJS project. The seed project and others have all directives in one file, all services is one etc. This quickly gets messy. Using different files for each, I have to include a lot of js files in the main page. Not sure what to do.
In our project, we created multiple sub-directories underneath the controller and services folders to organize them by business functions. It's fairly easy to re-organize the file structure in an angular projects.
Another good resource is a well made example app called angular-app [2], which includes security, a small backend, some crud pages, etc.
