Why remove a really useful feature like the save button? I just lost hours of work because of an accidental page refresh. BRING BACK THE SAVE BUTTON!!
The save button is present on certification projects, it’s on the right of the Check Your Code near the reset button and the help button
You can also always use Ctrl+S. This will work also on non-certification project, but the code is saved to local storage only. (cert projects save WIP code to database)
