There seems to be a small change in behavior of Artist & Album links from Track Information panel (working as the link to Library Filter).
I wonder if it's a designed changed in MB. Here's what I mean:
1. in MB2 clicking Artis/Album always showed the tracks of this filter from the whole library. No matter in which playlist or pannel u where. Always all tracks of the particular artist or album were shown.
2. in MB3 it is connected with the Search node. If the playlist/tab has "entire library" search node on, then Artist&Album filter tracks from the whole library. However, with "local node only" on, it filters out tracks from the current playlist.
I must admit I strongly prefer the MB2 behavior, seems to be more logic and intuitive.
