[LAU] Ardour: Region management

When creating a track with name 'elephant' and then recording onto it, regions are created with variations of the name 'elephant' (1.1, 2.1, etc). If there are several takes until I'm satisfied, several regions are created, and easily accessible from the regions list (View -> show editor list). Then I discover that I actually recorded 'giraffe'. I change names of tracks and regions to avoid confusion. Unfortunately the regions list does not update names accordingly - there regions are still filed under 'elephant'. Is there a way to update names in the region list? When copying and moving regions around, multiple and more or less identical regions appear in the regions list. Can identical regions somehow be ignored? Is it possible to use the regions list to navigate to that region in the session? And lastly, does anybody have tips for good workflows regarding regions and the regions list? Any and all input appreciated! Alf
