Items in the abuse log are triggered by individual edits (or other actions), yet the log does not link to the edit (or action) that was responsible. One has to go into the user contributions or page history and find which of the edits in there matches the diff they saw in "details" view, usually a simple task, but always an unnecessary one. There's an ID for the abuselog entry but it's not the same as the revision ID or log ID. It seems to me that the #1 reason someone is going to be viewing abuse log details is to find "log-only" things that have to be acted upon. So for edits, they need some link to the diff page or revision page for the edit, from which they can access edit, rollback and undo links (and any other links that might be there). Even just sticking the revision ID/log ID of the edit/action responsible in there would be better than nothing.
