Just thought I'd mention this : I commented out a Couch editable region (using <!-- -->), refreshed the template when logged in as super-admin and visited the admin panel to delete the region from the template. After a bit of trying and failing I realised that Couch didn't recognise that the code was commented out - it actually needed to be deleted.
Not really a problem - but it might save time for someone else if they read this.
