I've update the gist with the latest version of the macro that i'm using.

Beautiful script! Thank you very much. Working nicely on On-prem Confluence v. 7.2.1. To bad Confluence could not add this feature as default.

Updated script to handle failed AJAX

Also made a gist to tick all checkboxes on the page.
