I am getting tired of importing the same icons over and over again to differentiate one the key property or properties of the object. I believe the TableRecord refresh object changes its icon based on a ajax or non ajax call. Looking for more objects like this, but more geared on main OS objects:
Actions
Public
Function
Entity
Public
ReadOnly
Etc.
Having different icons would help in security validation by quickly indicating what is publicly exposed and to what extent.
