- "all comments" should be improved but it is not so simple actually. Especially for making detailed filter like what you suggest. It may sound simple to say it, but what kind of user interface would allow so complex filter?
Also many details depend on what is already identified (i.e. after that the vehicle is renamed), whereas the new comments are mostly about vehicles not yet identified.
- it is because the browser does not cache the page, so it reloads it when going back to the page. I haven't found yet how to properly avoid that. What I usually do is to open links in new tab/page, it is much easier than going back each time.
- forum is a separate server made by someone else, actually not linked to the site.
- stats may be added some day
