how can Contact Audit log more informative

Content

while working with Staff account or Incidents i noticed that there are few times when we have no answer to say what exactly change happened. like when you change the category or add private note into incident, Audit log says 'Edited',
on another situation, when you change display name, or add something in Staff Account, audit log always says 'Edit'.

is there any way to identify what exactly happened.
