When you complete a form in Natural HR, by default the system shows icons which indicate the "visibility" of fields. For example:
These icons can be "hidden" if desired, to present a "cleaner" form for completion.
To change this setting, go to Company Settings:
Administration > Company > Settings > Company Settings
On this page, scroll down to the "General Settings" section. In this section, there is a setting called "Custom form read-only icon visibility". Set this to "Hidden" to hide these icons.
