Currently, the column description is only visible when the column is active – which is not very practical.
Visible column notes would be very helpful durring events with many columns.
I suggest making the column description always visible as, for example, a tooltip.
Descriptions visibility could be toggled with a button or checkbox in settings.

Alternatively, I propose adding a generic input type such as a "Note", which would do nothing except display text on itself in the dashboard. A few lines of text should fit within a small rectangular area.
