Zen unwrap unfold vertices not founded

Hey. Yes, you are right. In the latest version, the Unfold Vericees option has been removed from Zen Unwrap operator because it is no longer necessary. Now you can select vertices and simply perform a standard Unwrap (U hotkey). In earlier versions, this caused the selected polygons to detach, but now the operator understands that it is working with vertices and simply relaxes them. The Relax Along Axis operator has been added to relax vertices along a specified axis.
