Yesterday I found in Linux Magazine 02/2006 a two site article about KPowersave (v0.5.0). As a colleague told me the same article was also in the german Linux User 12/2005. It's a littlebit annoying that the author did not try to connect me or one of the other (K)Powersave developers before writing the article. You can read the article here: "Ktools - KPowersave is an easy interface for configuring power management settings" [PDF, 710 kB].
After release the new KPowersave on kde-apps.org I found on kde-look.org new KPowersave icons. They looks like icons for Nuvola theme. Nice work! Download from: www.kde-look.org .
