Roadmappy stuff

Code Navigation

Quickly list controllers/directives/services etc in a searchable popup

Code Generation

Generate controller if they don't exist. Like ng="FooCtrl", generate FooCtrl

Autocomplete inside of {{}}

Would be a lot of work, but a good challenge

Autcomplete custom elements/attributes defined in directives

Again, a lot of work (with probably not that much pay off), but a fun challenge

Inspections

Analyze for AngularJS "code smells" (first we'll need to determine what those code smells are :) )

File Templates/Generation

We could easily one-up yeoman's code generation, but we'd still need to be very opinionated about the process.
