Hi

At the moment advisor icons are enabled only in tutorial mode.

Could you make them a configurable option so that they can be easily turned on instead of editing files?

Start by tracing where advisor icons are enabled only in tutorial mode and identify the existing configuration entry point. Add a user-facing option that enables or disables the tutorial UI behavior, then verify that the icons follow the selected setting without requiring file edits.
