It's so user unfriendly and anti-Wikidata tool that it adds all sorts of unwanted gibberish in the form of aliases like this one wikidata.org/w/index.php?title=Q2013&diff=prev&oldid=2337369192 that shouldn't be added at all. The fact that all these options are enabled by default is just so annoying... It should be disabled and made optional as soon as possible! smh

very confusing and buggy tool, it adds things I didn't ask for

This tool may be useful for newbies, but certainly not for experienced Wikidata editors, as no one in their right mind would use P854 in references. In case anyone else is not aware, this tool is unhelpful when it is being used in references because it relies on the incorrect (from the Wikidata point of view) P854 property instead of the existing Wikidata external identifier. I don't recommend it to anyone until the obvious major errors are corrected.
