I've would like to see ability to move to side the thumbnail scroller like a option in feature release, also ability to change sensitivity of a thumbnail scroll (it's too high right now).
People have requested earlier to change the sensitivity. We will consider this, but its a little difficult because position of thumbnails is proportional to horizontal position of mouse.
ok, I have noted your request, although all these positions make it hard to syncronize all elements and navigation without putting a lot of responsibility on the user
