This small plugin will hide the 'add widget' button to non admin users. Pretty useful if you don't your users modifying the profile widgets layout (Static profiles)
-Add Widgets only available to Elgg Administrators
-Requires Profile Plugin
I experience a conflict with the Homepage_CMS plugin (http://community.elgg.org/plugins/968182/1.2/homepage-cms) which is used for index layout. When 'Add Widget only for Admins' plugin is below that plugin, the index layout is crooked. When it is above it, then the "Add Widgets" button remains visible. regards.
