In case anyone browses the forum to figure out why this workflow stopped working after upgrading to Alfred 3, just go through the workflow and update scripts as follows: [e.g., tell application] "Alfred 2" → "Alfred 3".
@raguay.customct, this workflow is indeed the best. Thank you once again!
It may be my imagination, but it seems that this workflow is even faster on Alfred 3. Fantastic! :-)
