I think it will be great to have the small "Reply" button near each posted message in the case, which helps active users to communicate into the cases.
For example:
1) You see
Edited by User1 01/01/2011 [Edit][Reply]
1) Bla-Bla-Bla...
2) Bla-Bla..
2) After You have clicked on [Replay] button page redirects to case edit where edit box is filled:
Reply to User1 01/01/2011
1) Bla-Bla-Bla...
2) Bla-Bla..
3) And You may simply comment:
.> Reply to User1 01/01/2011
.> 1) Bla-Bla-Bla...
Ok, I'll do this
.> 2) Bla-Bla..
No, I think...
It may be shiped as a plug-in.
