In general, it’s also convenient to see where the posts are—in local sections or in the main English sections. If this were somehow visually displayed in the post history, I believe it would be a very useful feature for forum members and would make navigation much easier.
It is still possible to count accurately from the post history, any post that has been moved or deleted could be easily spotted as well and you can just count backwards to the timestamp. Every post is even label with their respective board. Also, ninjastic.spcae & the beta version are available for that too
