Listbox scroll bar size increase

Is there a way to increase the size of the horizontal and vertical scroll bars on a list box? On large monitors they are very narrow which makes them disproportionate when using larger font sizes.

That looks more involved than I was hoping for, but thank you.

It’s a small scale app that I’m writing during my spare time and other priorities for this app come first. I thought I’d see if someone had already blazed this path.

I’ll look at this again down the road. Thank you.
