Although there is some ability - it's limiting - and having more ability would help for the instances when you may need to see more on a screen.

In screenshot - the pink highlight - shows I can on some columns I can make thinner than the column title. But in some others the column title limits the width.

The name is a funny one - I can make it thinner - but the title reduces and the white space remains!

There are situations where I want to see more information on screen.
