Can you enlarge the Hue Range slider????

Maybe I'm getting old but I feel like the Hue Range slider is getting thinner and smaller. 
I know how to expand the pallet to make to expand the Width of the slider, but I'd like to also be able to expand the HEIGHT of the slider! Just makes the little grey bar between the top and bottom hues a bit easier to grab and move. 

It's just hard to slide with a mouse or pen which makes no sense because it's a super precise and useful tool.  Just make it bigger please.
