Make the attachment URL field editable in the web version

pooranis

I've noticed that for snapshots, the browser extension automatically fills in the URL field for the attachment. But there's no way to edit that field. Is there a reason for this? Also, there's no way to add a URL for attachments you upload yourself. So, I can't upload my own html pages.

Could those become editable fields? I'm specifically asking for the web version of Zotero, as I like to add articles "on-the-go" when I'm on my phone or tablet.

Thanks!
