Blue Line in XP Bar?

[BadBeans]

Hello,

I just recently started playing on P99 Green a few weeks ago. I noticed there is now thin blue line on the XP bar that when filled represented 1 yellow bar. Wasn't this a feature in the classic era of EQ?

Granted, I haven't played EQ since like 2003 so I can't recall if this was a feature added later but I was just wondering. I figured the newbie area was the place to ask!

Also, Thank You P99 developers! I appreciate it VERY much what you did for the world with this classic iteration of EQ!
