You are free to install this script/stylesheet for yourself, but it is not allowed to be used wiki-wide (e.g., in MediaWiki:ImportJS, MediaWiki:Common.js, MediaWiki:Common.css, MediaWiki:Fandomdesktop.js, MediaWiki:Fandomdesktop.css, or MediaWiki:FandomMobile.css), as it would violate Fandom's Terms of Use.

SandboxLink is a script that adds a link to the /Sandbox subpage of the user in the user dropdown menu of the global navigation. The sandbox subpage is where people experiment things such as developing a new style of an infobox, developing new experiments, elements and more. It can also be used for drafting purposes. This could be useful for users who often use their sandbox subpage.
