Vault deletelabel, renamelabel
 

In 6.0a, these Vault commands have no place to specify the required value for label (or for new label in the latter). Contrast to the Vault label command which does have an edit box for specifying the label. The workaround is to specify the values in the "Additional command line options" field. I guess they ran out of space in the dialog.

Thanks for mentioning this. We'll update the Vault action to support dedicated label fields for these commands.
