It'd be nice if you could enter more than one URL for each reference. I often want the URL for the original reference, plus the URL for the pdf of the full paper in my dropbox account.
> any URL that's not suitable for citation (e.g. your dropbox link) should be attached as a link. You can have as many of those as you want per item.
It would be nice if that were done automatically during merging. :/ Now I have to track down all those links I just deleted because I didn't realise this was supported.
Attached links are moved to the merged item during merging. Zotero doesn’t really have any way of know if inappropriate URLs are stored in the URL field for an item.
Upgrade Storage
1. Right-click the item in the main panel.
2. Click “Add Attachment”.
3. Select “Attach Link to URI”.
▶ Do this in the main (center) panel of Zotero, not the details (right). ◀

This wasn't immediately obvious to me, so I wanted to clarify. Thanks to adamsmith for the helpful answer.
