Every day I love small window managers more and more, actually I starting to think that there is no need for Gnome or KDE, I am using latelly OpenBox and was using fluxbox before.

One of the differences between these light weight Linux window managers and the Desktops like Gnome or KDE is that when you add or install a new program it is not automatically inserted in the menus, so you need to add it manually or may have a program doing it for you.

If you are using OpenBox you need menumaker First install it.

Arch Linux

sudo pacman -S menumaker

Gentoo Linux

sudo emerge menumaker

Once it it installed just run it:

mmaker -vf OpenBox3

For Arch Linux

mmaker -v OpenBox3

For Gentoo Linux.
