I understand this.
But why is this simple feature not in the current version of foobar but in the old one?
You probably had a "full" or "special" installer of 0.8.3, which had Columns UI bundled.
With the installer for 0.9.x versions, Columns UI is not included, thus it is a
optional component. To answer your question, I don't know why - perhaps the foobar devs didn't want the installer to be too bloated.
BTW you can download the component .dll here.
