Let's say I want it to display only 15 lines of text (but have the number changeable), when a 16th line is wrote it deletes the first line. Example:

Line 1: Bob: Hey guys, 'sup?
Lines 2-14: blahblah
Line 15: Harry: Not much. You?

Bob is going to answer Harry, now the chatbox appears as:

Lines 1-13: blahblah
Line 14: Harry: Not much. You?
Line 15: Bob: Pretty good lately.

I dislike scrollbars for something like a private messaging system, and would prefer to do it this way.
Edit your output element. Go to options. Under the huge text input, it asks for the maximum # of lines you want. Enter 15. ^_^

Is this a new feature, or have I just not explored enough?

You haven't explored enough.
It's been in for quite some time now with the 4.0 release.
