When an issue gets quite long with various comments from people, it is hard to see the history. You have to scroll to the bottom, click the "history" button and then scroll back to the bottom to see the history again after is has posted back.

Could the history be shown at the top of the page, and where it says comments have been added, actually add an anchor hyperlink to that comment to form an index/contents of the issue? This is a nice to have, but the history is awkward at the bottom when the issue has many longer comments.
