Re. Panes:
to set a custom name, you must first untick "auto-name"
Note: You cannot rename the stock 'audio, image and video' viewschemes
Re. Viewschemes: (assuming you'd like regular audio, with a classical 'child' viewscheme)
Right click on audio in the tree and choose 'edit viewscheme'
Set your panes the way you'd like for regular audio.
In 'step 4' type (without the quotes) "-g=classical
click OK
None of your classical tracks will show up now when you click on audio.
Next..
Right click on audio again, and this time choose 'add viewscheme'
pick panes you desire for your classical tracks.
untick 'auto-name' and name it classical
make sure 'honour parent scheme search strings' is unticked
in step 4, type (without quotes) "[media type]=audio g=classical"
this viewscheme will only show tracks whose genre is classical
For both of the above, use the 'customise current view' dialogue to choose which columns you'd like to see in the file list, and also to set any desired sorting.
