It's very easy to get into a story that's locked by someone else, edit it and assume you can save those changes. That doesn't work, of course — the file is locked by someone else. There's a red warning at the bottom of the asset, but it's easy to skip — especially if you're starting at the top of an asset.
Anyone else interested in a more obvious warning? A pop-up would be very helpful to our editors: "This story is locked. Would you like to read it?" (Or something similar.)
