Make Categories Box Taller

Hi!

I’ve checked around for this and the only info I can find is from 5 years ago.

Does anyone know how to make the ‘Categories Box’ “taller” within the WordPress Post Admin/Dashboard? I’m using the twentyeleven theme and even in trying to hack the core files, we can’t track down the css. It’s looks like the inside scroll box has a max height of 200px-ish. We have a ton of categories and would like to make that atleast double the height.

Any plugins that work for this, or anyone know of the css to tackle this?

Thank you!! ??
