I have created a script for Wikidata, which allows to easily change order of values in a Wikidata statement — https://www.wikidata.org/wiki/User:Tohaomg/rearrange_values.js. I request for a gadget to be made out of this script.

I have tested the script on https://test.wikidata.org, and it works fine, apart from an issue that it fails to launch in Opera for certain interface languages (so far, I have no idea how to fix it, but this does not do any harm, so it can be ignored for now).
