Download Failure Recovery

Currently:

1. Sometimes download failures are silent, meaning that they do not invoke alerts.
2. All the failed downloads are removed from the download manager automatically.

This is in contrast to how apps like Safari are handling these situations: the failed download would remain in the download queue with a resume button.

Judging by the fact that videos being downloaded prior to app relaunch would resume their previous process, the system does not remove the temp file associated with each download task, at least not immediately.

So it is not too far fetched to suggest that recently failed download could be resumed from the point of failure. Also, would u consider changing failed download notice from alert window to notifications, which would be less interruptive.
