I made a new admin-only page, Tiki_org Custom Code, to keep a copy of the CSS, JavaScript, etc. that is input on tiki-admin.php?page=look#contentadmin_look-5 and keep track of changes. Any Customization additions, deletions, edits, etc. should also be made here to keep the record accurate. This is to keep a history of that data and also have a quick backup available.
