Some updates have been done on both audioserve server (now in version 0.6.0) and Android client (now in version 0.7.0):

• on server collection directory structure can be cached in memory for fast search – use option –-search-cache
• search results also contains folder path (both Android and Web client)
• Web client –  cached parts of audio in player are displayed as a green bar
• Android client has now bookmarks (in addition to automatically maintained recently listened) – bookmark  button is revealed by swipe left gesture on the item
• Advanced playback options – speed and skip silence – pull up the playback controls to see

Just for comparison –   see memory requirements of audioserve vs airsonic:
