Trevor Morris has posted a bunch of new and updated scripts on his excellent Web page:
o Center Layer - a simple script that centers the active layer; updated to work with any resolution (thanks Luis Guerra!)
o Close Without Saving - presents a dialog, allowing you to close the current document, all documents, or all except the current document, without saving and without prompting to save changes
o Close Inactive Without Saving - closes ALL documents, except the current/active document, without saving and without prompting to save changes (included in the above script)
o Rename Layers - renames all layers in the active document, up to one group deep, using the supplied pattern (and numbers them); updated to include zero-padding, configurable name separator, etc.
They're all freely available from here:
