This interface is helpful... to a point.
The green check shows you that you've gotten a response, which is useful the first time.
After that, it is just noise.
I've now got over half a dozen tickets going, quite a few with "back and forth" happening. The green check tells me nothing now. I literally have to go through each, one by one, to see if I've gotten a new response.
I think WPMU can do better than this. I realize it would get a bit more complicated to program. You'd probably need another icon or something. But it would sure help...
Can somebody please look into this? I'm sure I'm not the only one who is getting irritated with this.
