If I am looking at a sentence and I click the button that writes a post about it to a forum, there’s nothing that allows anyone reading the post to find the original sentence, other than the text of the sentence (and its translation). It would be nice if a link to the sentence and/or the name of the collection containing it was automatically written to the post.
Knowing the collection is important for a number of reasons. One is that the new Fast Track was assembled by a different procedure from the older collections, one that is supposed to make it more error-proof. Discovering a mistake in a new Fast Track sentence can indicate that even this newer procedure has problems and needs to be improved.
