I’m someone who doesn’t store media after I’ve watched it. I download, watch, and delete. Unfortunately, this is a problem when looking at the calendar view, because things that were missed or couldn’t be found at the time can’t be separated from things that I have already downloaded, watched, and deleted. I’m much happier with NZBDrone over sickbeard in almost every other way, but at least sickbeard could handle this pretty simple thing.
EDIT: Okay, apparently this is a bigger problem than I realized. I had read that if I let NZBDrone download and rename the file, it would remember that it had done that, and it would not try to download it again in the future when it was missing from being deleted. Well, I even used NZBDrone’s interface for deleting two shows that I downloaded and watched tonight. Imagine my surprised when 5 minutes later it’s wasting my bandwidth re-downloading them.
