Post ID number

• Post ID/comment number is not fixed but every time a new post is creater the number 1 is re-assigned to last entry.
• This makes it hard/impossible to make reference to a prior post using a simple ID number.
• It wold be better if the post number at the top right is assigned in order of creation and never changed.

This is something I have asked before but no action was ever taken, is there any reason why PP does not consider it an improvement?
