The current functionality to filter history I cant figure out who would get value from that.  At the least, without putting to much effort into it, you should provide a dropdown for filtering "result" types - I rarely ever care to see "contact linked"  and "field changed"

 

I do not want to turn off the logging of these, it is just that in viewing the data, I dont care to see it 99%of the time.

 

This is something I would have expected to exist in the applicatoion long ago
