iTerm2 - hide split pane title bars?

Question

After recent update of iTerm2 the split panes look different:

This is how it looked before (some random image found on the Internet):

Is there a way to get the original look back or do I have to get used to it?

Edit: just to avoid confusion, what I'm concerned about are the "header" lines, the "(x) Default" thing. I'd like to have just a line there.

Edit 2: it's in this changelog:

- Add title bars to split panes that show the title. You can drag 
panes by their titles, and there is a menu and a close button in it as 
well.

Answer 1

Turn off prefs->appearance->show per-pane title bars with split panes.
