2 issues with Subsonic

First of all I love this app and its far better then the other music servers i was using. But I have 2 issues that may cause me to stop using it though.
1. If I click Play All for an album it loads all the songs at the bottom but it does not always play them all, sometimes I have to click the next song. It seems to happen irregularly.
2. Is there anyway to allow users to view certain folders and not all of them? I have multiple music folders and some have the same cds in them so subsonic shows the tracks multiple times for those albums if its set to All Music Folders, or is there a way to assign a default folder for each user?
