but I wanted to see how it works with 1 single normal line and I think that maybe the images are too big and it's very close to the scroll bar ... Maybe once it could be reduced a little, what do you think?
Hmm you know, I really like those gigantic 1-row thumbnails
but it's true they are a bit overwhelming, and also cover up a bit of the scrollbar. It would be fairly easy to reduce the size of the "zoomed" thumb, a bit more difficult for the "non zoomed" ones. I'll play with the settings and see if I can find a good compromise...
In the meantime, if you dare, you can change the zoom ratio yourself
look for this line in the code
local selectorscale = (rows == 1 ? (vertical ? 1.15 : 1.45) : ((prf.SCROLLERTYPE == "labellist") ? 1.4 : 1.5) )
selectorscale is the target zoom ratio of the current thumbnail. To translate my obscure variable system, if there's a single row in the layout, scale is 1.45 (in an horizontal layout like yours), otherwise, if the scrollbar is with labels it's 1.4, while the "default" is 1.5. Try to play with this number, puttins like 1.3 instead of 1.45 and see what happens.
