scheduled updating of packs? and also, i'm not sure if this is possible, but, say you want to download ASOT episodes 300-450. it'd be nice to specify that and download all at once.
Or triggered by adding a new cue or by change in a cue. Though, that might be overkill as I sometimes make many small changes to a cue. But, with timestamps for last edited it could check once a day if a category needs refreshing.
Downloading multiple cues would be more difficult, might be possible with a lightweight Java application that just streams from the server. So, Java webstart (no download needed), and integrate it to CueNation's search and then just click "Save All".
