Not sure this can be done even with script (and even then it'd be modifying the DOM, a not officially supported action)

That's what I figured. My answer to the end user was to scroll to the right or get a bigger monitor, but that's not always accepted so well 😄

The best answer is to build a saved search with only the information that certain people care about and add that as its own sublist. There's just too much information in the sublist to make it very useful for the average user.

^^ have done this for many users and they seem to like it

Yep, that's what I ended up doing, in large part for that exact reason @Sandii
