The biggest problem I have is the lack of docs on what any of this means.  I have no clue what Weight and Cached mean exactly – I do have some vague guesses.  Hopefully, that will be resolved when the Help file is done.

Also, I noticed that you can right click and set priorities, which surprised me.

But there is some mysteriously stuff in there like “unknown/system” and “unknown/unknown”.  I have no idea what they are.  Both are 6% cached.
