Yep, you got it the second time. As the NZB's that are auto imported are grabbed automatically, I want to run my eye over them before they are actually processed and downloaded by Alt.Binz. That way if someone decides to make a silly edit to an online database, or some other situation arises that means a whole stack of NZB files are grabbed which I don't really need, I can review and fix them before they are actually downloaded.
I've tried unticking the "connected while idle" option, and yes, it disconnects, but if a new NZB is imported, it reconnects and downloads the collection before disconnecting again. Ideally, if it completely disconnected and didn't reconnect until I re-clicked "connect" that would work for me. I still think the "auto-import as paused" would be a better option, as that would mean I could a approve a set of collections to download, and if any came in while it was still downloading and connected, they would not download until I had a chance to approve them.
I hope this is making sense,
Cheers,
Murf.
