I agree. Expanding the message would give me the comfort that i didn't mess up the link (which i tend to do, which is incidentaly why i love the preview function when doing a writeup).

I just noticed something else that's a bit confusing, at least for me(*): When sending via Message Outbox, the only way to see if the message was actually sent is by scrolling down and looking for the "recently sent" lines in the chatterbox nodelet.

Any chance this could show a generic "Message sent" status below the "Deliver" button?

(*) I'm so used to how my own web software always gives me feedback after sending a form. Even when editing some master data entries: Select line from table, which opens the detailed view. When you submit it, it reloads the same detail view in a very short time. For a brief interval, a green text appears near the top of the page, telling you that the updated was accepted. Yes, it's a bit tacky. It's the equivalent of a keyboard button lighting up to show that you have pressed the button. I mean, childish yes, but that's basically what phones and gaming keyboards do. So why not a webpage? "more feedback is more better", i think
