As a part of my GSoC, I have created a script tabbedWindow.js. So before deploying it on the MediaWiki.org, We need and want to deploy it on the Test Wiki. So that we and other users can test script
Script JS Code:- https://www.mediawiki.org/wiki/User:Jayprakash12345/tabbedWindow.js
Script CSS Code:- None
Gadget Text:- It embeds an OOUI tabbed window on all pages in the API namespace.
It should be enabled by default for all users.
