But if you're only interested in Waiting:Joe, does it matter what is being shown in Waiting:Bill or Waiting? My suggestion was merely that you'd have everything separated out by context and could thus look at only the context of interest at the moment and more easily ignore the rest, instead of looking at an ungrouped list where you had to inspect each item to see if it had a context of Waiting:Joe...

"No, it didn't help" is a perfectly reasonable answer to my original question, too :-)

Ah -- now that I reread the message to which you were responding, I see that that poster didn't have the structure I was envisioning (a waiting context with subcontexts for each person). My grouping suggestion wouldn't help there, I agree! But you could make a perspective that picked up only those subcontexts, right?
