At the moment, Wikidata has four/five preferences options for automatically adding pages to the watchlist:
- "Add pages and files I edit to my watchlist"
- "Add pages and files I move to my watchlist"
- "Add pages I create and files I upload to my watchlist"
- "Add pages where I have performed a rollback to my watchlist" (if the user has these privileges)
- "Add new files I upload to my watchlist"
I currently have 'edit', 'move', 'create', and 'upload' ticked.
When creating new pages other than by the normal on-wiki interface - in this case, by using Magnus's quick-statements/WIDAR tool - the newly created pages are not watchlisted.
Likewise, edits done through WIDAR/mix-and-match do not seem to cause the target pages to be watchlisted.
I have not yet tested whether moving a page on another wiki will cause the linked WD page to be watchlisted.
It would be good if these preferences were consistent for both "on-wiki" and "off-wiki" edits, given how widely used these tools are for editing Wikidata. (I'm not sure if this is a Wikidata-specific issue or a MediaWiki one, but tagging as WD for now.)
