Problem: Currently you can't quickly copy statements from an item and paste them to another item. Instead you have to do it manually one-by-one for every item, or use the semi automatic tools. There are items with many statements that all could be added to many different items.
Who would benefit: Not all users want to use external tools, so this would help users from other projects to edit Wikidata.
Proposed solution: Create an environment where users can select statements (by checkboxing them?) and then copy them. Then they can open another item and paste selected statements there.
More comments: I don't know is a visual environment the best implementation, or should there be something like wikitext that users can copy and when pasted and saved, it will be migrated to visual mode.
Phabricator tickets: phab:T161259 "moving/copying statements to other items"
Unless I misunderstand something, the moveClaim script only does them one at a time (though it does make them easy to move) - the proposal here is to select many claims at once to copy and/or move to another item. ArthurPSmith (talk) 20:10, 15 November 2017 (UTC)Reply[reply]
In such cases, moveClaim requires just two licks each for the second and subsequent items. For "many statements that all could be added to many different items", I use QuickStatements. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 23:02, 15 November 2017 (UTC)Reply[reply]
May be I mean another thing, but what about moving some statement to another property? --Infovarius (talk) 14:04, 11 December 2017 (UTC)Reply[reply]
