No, you are looking for the main window to display entire albums instead of individual tracks if I understand you correctly. The only way that is possible is to switch to "Art" view. View > Show art.

I understand, but the criteria appear to be drop-down menu choices.

Collection Name: Blues
Search Criteria:
Property: Genre (menu selection)
Condition: equals (menu selection)
Value: Blues (result)

So what do I enter and where?

No Criteria for Collections are set under File > Manage Collections by editing a Collection.

I don't understand. The criteria for creating a collection are determined by menu choices.

Use Criteria Album is Known?

Is it possible to setup a collection view to show albums-only in the main window (not the tree)?
