1. I like the Application Error Log functionality a lot. However, it becomes time consuming to inspect it date by date and directory by directory on a multidirectory server. Ideally, I would use an existing error class to write a custom error report by date, selected namespaces, etc. Does such a system class actually exist? Not that I found. The detail level on the screenshot below is enough.  
2. Some Application Error Logs go back a couple of years and load for a long while. Is there any programmatic way to clean them? Deleting errors in GUI date by date and directory by directory is rather tedious as well.  
3. The ^ERRORS global has an unclear structure to me and I doubt it is related to the Application Error Log anyway.

Thanks in advance,
Anna
