Occasionally, I still use that to create new items for films ..
As it tends to get slower (when loading duplicity) and cluttered (many non films being displayed), it might worth doing an slight overhaul.
I think in all cases where there is no item with "instance of (P31): film (Q11424)", creation could be directly in Petscan. If results are displayed in duplicity, using -haswbstatement:P31=Q11424 could help.
(I probably wrote something similar sometimes before)
Anyways, good to see that Petscan is back. Thanks for that!
