What feature/utility/app are you surprised is not installed by default in Linux distributions?

Sometimes, more is less.

Also, sometimes they have an old version of less. There was a change in the past, I don't know, five or so years that made the "exit if less than one page" flag behave better. I don't remember the specifics but it made using it as a fit pager way better. It used to be that it was difficult to have it act like cat when the output was less than a page. But newer versions support it.

What distro was this?
