In the case of filtered ng-repeats (ng-repeat="type in types | filter: search") it would be really useful to add something like $collection to the transcluded scope at line L276.

Then we could easily access the filtered collection in our ng-clicks and ng-class functions like we access $index.

I imagine it would be changed like the following which wouldn't incur much overhead as it is just passing an object reference:

var updateScope = function(scope, index, collection) {
  scope.$collection = collection;
  ...
};

// then at line 364 and 377
updateScope(block.scope, index, collection);

I could probably run up a PR at some point if this is acceptable?
