Problem
Dropbox’s screenshot pop‑up replaces macOS’s floating thumbnail but can’t be dragged into Messages, Slack, Finder, etc., forcing users to hunt for the file.
Request
- Make the Dropbox thumbnail draggable to any app.
- After the drop, keep auto‑upload and markup intact.
Why it matters
Faster one‑step sharing, consistent with native macOS behavior, and fewer users disabling Dropbox screenshots.
