Quick Chrome Addon Enhancement

I already use a small custom Chrome extension that imports a list of names from an Excel file, lets me edit the list, and then produces a plain-text draft I can paste wherever I need. I’d like to bolt on one more action that runs immediately after that draft is generated. The exact behaviour is simple and I’ll walk you through it when we start; it should be no more than a half-hour tweak for someone comfortable with JavaScript and the Chrome extension APIs.

What I need from you:
• Update the existing codebase to add the new post-draft action.
• Keep the current workflow intact—Excel import, list editing, name selection, draft creation must remain unchanged.
• Provide clear in-code comments so I can follow the adjustment later.
• Supply the rebuilt extension (packed or unpacked) plus any modified source files.

If you’ve edited Chrome extensions before, this should be quick money and a fast five-star review.
