Smooth scrolling thumbnail area

[Shinkir0]

It would be nice to add smooth scrolling in the thumbnail area.

And also, It's certainly not necessary and it is unlikely that it can be implemented exactly as it is there without redesigning half of the program, but, I also like the way the thumbnail sorting looks in the Allusion program, horizontal and vertical masonry, and the smooth scrolling is well done there too.
