What version are you running?
1.5 beta 3 (dev)
Describe the enhancement and the motivation for it.
Enhancement:
It would be really nice if there was a function for the reviewers so they could 1) edit the diff in-place and 2) display the changes for the original poster to confirm/deny, much like how track changes works in Word.
Motivation:
I am currently working on an open source game. Unfortunately a number of the developers do not speak English as their first language and leave cryptic comments, when a short in-line modification to the code would me much more enlightening to both parties.
What operating system are you using? What browser?
Ubuntu 10.04 and 9.10 and Firefox 3.6
