Everyone has wanted a way to remove all checkmarks in the Remaps Managers "Never Deletion" column, so, I wrote a quick script that adds a checkbox for you, which, when clicked adds/removes checks to all the checkboxes in the Never Delete column.
Here is the code that you need, just add it as the Address/URL of your bookmark:
javascript:(function(){var doc=top.sq_main.document;var mainDiv=doc.getElementsByClassName('sq-backend-table-header');for(var i=0;i';}}})()
Please let me know if it works for you, or what I can do to improve this. (Tested in Safari/Firefox for Mac)
NOTE: If your the asset id of your Remap Manager is something other than 19, you must replace 19 with your asset id. Also, this will not work in Internet Explorer.
