Experimental settings
From MoodleDocs
An administrator can enable certain experimental features from the Experimental settings page of Site administration.
An experimental feature is defined as a feature which require additional testing and bug-fixing.
- Context freezing - this allows an administrator or user with the capability moodle/site:managecontextlocks to make categories, blocks, courses or course content 'read only'.
- Safe exam browser
- Path to SassC - this setting allows an admin to specify the path to a binary file that will be used to compile SASS. When this field is set (and valid) - the provided compiler will compile SASS code instead of Moodle's built in PHP compiler. This makes the process of compiling SASS significantly faster. (see MDL-61394 for further details)
- Drag and drop upload of text/links (see MDL-22504 for further details)
