I really, really like most of the Miu theme - it's great work. The original scrollbars kept me from using it though, since I didn't think they fit very well with the rest of the theme - so I dug a bit on the file, and managed to change the width and the colour of the scrollbars, as well as a few other minor things that I don't remember. This was meant for my own personal use, but I thought that perhaps others felt the same way I did.
All credit should go to dashua, the original author. :)
