With the introduction of link conversions, I think it would be nice if you could run a rebuild or something similar to update all of the links to show the page titles (or the current format if you changed the format) or vice-versa if you later decide you prefer the raw URL. The only way to do so right now is manually by editing each individual post from before the implementation, which would be tedious, especially on large forums. Edit: Maybe even make it a cron task. That would be useful for XenForo especially because of the threads that are moved from XenForo Bug Reports and XenForo Suggestions to Resolved Bug Reports and Closed Suggestions, respectively. The resolution prefix will be added in any links that were posted before that.
