Hello @a1exsh,

Nice, I prefer this way. :)
Could the top of the scrollbar be aligned with the top of the first checkbox and the bottom of the scrollbar aligned with the bottom of the last checkbox?
For a perfect position of the scrollbar, we should also move the scrollbar 1 pixel to the left to have the same distance between, the left edge of the checkbox and the left edge of the window, and the right edge of the scrollbar and the right edge of the window. :)

Hi, @LeHerosInconnu! Aligning to the bottom of the last checkbox is strange, because people always expect smooth scrolling, while this condition will bring ragged scrolling.

Okay, the best possible has to be done. :)

@a1exsh , thanks a lot for this fix!

@LeHerosInconnu we could also drop the shadow from the scrollbar, to make it look even closer to the original. Too late to do that in this PR, but maybe sometime later. ;)
