I am using Okular under the Gnome environment. My issue is that the scrolbar has a rather low contrast (at least too low for my tired eyes) which makes it hard to find and use. I was wondering if there was a way to change the colors of the scolbar? Or maybe should I do a feature request?

Here is a screen capture example: the contrast is a priori not too bad but low enough for my eyes so that I have to scan through the bar in order to find the handle and I find this a bit tiring.
