Actually, it's your tool that makes changing the plugin irrelevant. <img src="smileys/smiley2.gif" border="0" align="middle" />
Edit: If it helps, my width routine wasn't automatic, you select one or more letters, and change the width, which moves a red line next to each letter. One exported it was meant you would load the transparent PNG into an editor for embellishment, resized smaller and save.
Back in my editor it asks what size the final image would be saved at, and recalculated the "copy and paste" widths to match.
(Not that much of that part was done yet.)
