Great workflow!
Would it be possible to detect whether the file name already exists in the target folder (or even some adding some suffix like "-copy" to make the Dropbox upload still work)? Right now it gives an error message saying that the token is incorrect.
Also, the clipboard URL contains a newline at the end, could that be removed in the script?
[bTW, if a folder name contains a single quote, the workflow fails as well, but this is kind of a corner case.]
