i try to copy the bz2 file but i cant..it doesn't allow me..ah..neither to extract..any help?

ups, sorry, yeap. we must copy the bz2 content to /usr/share/screenlets/Sidebar/themes

how do i apply this themes?

This is exactly what I needed, it has a lot of options and I really like how it looks.

How do I apply the themes to the sidebar?

I highly recommend this package - the sidebar themes are excellent. I use the Vista one for preference but there are a few very attractive dark ones in there as well. If you have screenlets, get this ASAP.

Screenshot please.
