See through menus?
 

I keep seing screenshots of people that have see-through menus and I just wanted to know how they did it. It looks really cool and I have been going through all the settings, but I just havent found a way to do it.

If you're in KDE, then go to the Control Center->Appearance & Themes->Style->Effects and set Menu Effect to Make Translucent. Some options should become enabled at the bottom where you can set the amount of translucency.

It's under Start menu -> Configure your Desktop -> Look n Feel -> Style -> Effects.
