Bug 248393

Next enhancements are very needed: 

1) autocomplete 
1.a) Say we have 

someModule.{controller|service|cofig|run|any}('MyController', ['$scope', 'dep1', 'd<Ctrl+Space>', function($scope, dep1, <place to put new dependency>) {
    ...
    $scope.aMethod = function() {
    ...
    }
  ...
}]);

In dependencies declaration when starting to type "'d<Ctrl+Space>" it could be good to see all services, controllers names that are declared angular way in all JS files of the project.
1.b) On dependencies usage if I have a service:
myModule.{service|factory}('Service1', function(){
return {
 a: ...,
 b: ...
});
in Controller or other service that uses Service1 : myModule.{controller|service|factory|any}('MyController', [ 'Service1', function(Service1){
return {
 var myVar = Service1.<Suggest here proper autocomplete values first: a, b>
}]);

2) Ctrl+click on a declared dependency could open corresponding modules part.
