I've just been experimenting with adding a quick-statements generator to
https://tools.wmflabs.org/ws-search — search for something, with 'linked
to wikidata = no', and then each row of the results has a popup with
code you can copy and paste into quickstatements.
I don't know if that sort of thing is useful. It's not working with many
fields yet, but I'm finding it faster than entering the basics manually.
