Each issue has 4 tabs - History, Notes, Property Changes, Support Discussion
The History tab contains everything about the issue.
The Support Discussion tab contains only the correspondence.
The Property Changes tab contains changes about the issue.
The Notes tab contains both comments and correspondence.
I would like to have a tab to separately indicate only our internal comments on the issue.

This is because the emails can be very large, and it is difficult to keep track of the comments we make in the issue.
