Twentyninetimes is asking why the 'Apply Changes' button appears inconsistently when editing modules, particularly in grouped/repeater items, and how to disable it for instant updates.

Evelynn explains that the 'Apply Changes' behavior is triggered by JavaScript in the module.js file. Moving JavaScript to {% require_js %} in module.html instead of module.js resolves the issue. Twentyninetimes confirms that removing JS from module.js worked.
