It would be nice to add additional features to the audit log, to allow administrators to better audit what and who is making changes to things.  

A few items that would be very useful:

• Communication log - record of both text and email communications sent via Ximble (open shift notifications, confirmations, etc.) So when someone says "I never got that", or "I didn't know", there is a way to actually prove a notification was sent.
• Time off audit - who approved John Doe's time off request, and when was it approved?
• Shift Pick-up audit - who approved John's shift pick-up request, and when was it approved?
• Location - I can see that John added Jane to a shift, but at what site was she added to?
