JRemote or "MO 4Media"
Gizmo can operate as a MC remote as well. As in, send up/Down/Left/Right/OK commands to a MC Server, in addition to selecting and playing tracks locally or on the server, or any available Zone.
You can copy an Album name in Panel, and then use it in the search box. Quote it to get an exact match. But of course it will still return a list of files in the Album.
Panel now accepts Search Expressions as well, so try a few of those. i.e. Search for "[Genre]=Jazz -[Year]=[]" or similar. Yes, you need to know field names and expression functionality.
Try some stuff like that. Search the forum a bit. There have been some discussions.
