At work I've implemented a super simple system where frames with file names that match some simple patterns are put in bold. This helps enormously while not hiding information that can be crucial at times. 

I'd recommend people try this approach and see how it feels. It's very easy to implement compared to the alternatives suggested so far in this thread. I'd also argue that even if the more complex hiding methods mentioned are implemented then this method can still be very useful on top of those other changes.
