For those having trouble connecting to sabNZBd make sure your url to your server is correct. Should look like this (http://xxx.yyy.zzz) No trailing slash, port or anything else. I'll come up with a more fool proof method of setting your sabNZBd server in a future release. As for the reports of it not working on Galaxy Nexus, that's my main test device, it works, check your settings please.
The new Pro version of the popular NZB Mobile app provides many additional features to the already powerful NZB tool. Pro features:
--Long press to queue multiple items quickly
--Full featured native SabNZBd client replaces the clunky webview(rearrange,delete,prioritize,etc)
NOTE to comments: I really wish I could give you comments, but they just aren't returned with the API for newzbin or nzbmatrix. I've asked FLASH from nzbmatrix to include them in his next API update, so hopefully we can get them in at some point. As soon as the API supports them, they'll be in the app.
