Description
The default button text for 'unlimited' fields where you can add multiple items is "Add another item".
You might want to change this.
This module lets you do it per field bundle - there are a couple of text options (for add and remove) added to the field edit screen.
NB: this is not the 'Save and add another' button for an entire content type, just the one that handles the javascript for individual fields with multiple entries.
