Feature request: Read-only mode for article and collection assets

There are occasions when we have assets that are still being worked on, but that have information or elements that are relevant to people other than the person working on the asset. It would be nice to have a means of opening an asset in a read-only mode so that it is not locked by the person viewing it, but is not in danger of having conflicting edits made. This kind of thing would also allow editors to at least read and give feedback on an asset while the author has open.

Here's an example: A reporter is working on a lengthy Sunday feature that has a massive gallery attached to it. She is actively working on the asset, but does not currently have it open. Another employee is simultaneously working on a video to accompany the story, and needs information from the story and photo assets from the collection in order to produce the video. But if the second employee opens the article and collection to get the necessary information, the reporter can't make any edits to the story or collection, because they are locked. A read-only mode would allow the video production employee to open and view the assets without preventing the reporter from opening and editing them.
