Purely a UX kibitz: I'm in the middle of a lot of heavy downloading, on a flaky Internet connection, so about half of them are timing out. I wound up moving over to Chrome for those downloads, and was going to post to the effect of, "Orion doesn't have resumable downloads" before I discovered that I was wrong.
IMO, the little retry icon in the little yellow button is too subtle for those of us who are older and have slightly weaker eyesight.
Chrome shoves the big "Resume" button in your face; I'd recommend that Orion be similarly unsubtle.
