Folder navigation in tags section
Add folder navigation to the tags section.
Once the folder selected, the tags list will display tags in that folder (and sub folders) and the search box will work for that folder (and sub folders).
(searching the whole collection is too slow with a huge collection of music)
Exactly my thoughts.
Yes, nice idea. I'd like to add a per-album tags page too but a folder and multi sub folder filter also has its uses.
