how to see what has been changed in an issue with email alerts

I am just evaluating if we can use webissues 1.0.1 in an international team with different timezones.

Email alerts are important for us, but when I get an alert (All Issues / Immediate Notification) then I cannot see what has been changed in the issue.

The issue history could help here, but I cannot see here that a comment has been edited or added or deleted, and when an issue has many comments it seems to be impossible to figure out what has been changed.

We did use mantis before, and while the interface of mantis is ugly, it sends very detailed email alerts, one separate alert for each issue, exactly saying what has been changed.

Is there a way in webissues to get more detailed alerts, or to better see when looking at the issue what has been changed?

Thanks
