Have anyone found the event (if any) that are triggerd when the Summary is Saved. Have of course tried UnifiedFileChanged andUnifiedFileCheckedIn.
Have tried to look with Refector but there is a lot of interface and abstract classes so I havent found anything.
I think there was a discussion about this on EPiCode a few months ago.
I think the result was writing your own file manager, but then again, it was some time ago.
