Workflow status in REST API searches

I want to search for features / releases that are not shipped yet.

Currently, the aha REST API does not offer "workflow status" as a search parameter. Further, the API response does not indicate the status in the feature/release "shortened" json representation.  Thus I have to send a new REST call for _all_ features/releases in a response,  always, to determine their status.  The end application consuming the API becomes sluggish, as well generating a lot of uncessary network calls towards you.

Please add workflow status as a query parameter in the API.

Please also add a way of letting me specify additional attributes to include in my search responses (f.ex if I could get status + a custom field, I wouldn't need to lookup each feature)
