Krcstat is a graphic replacement for the Gentoo rc-status and rc-update command line utilities. It can be used to check that all your services are active and generate an alert if they are not. You may easily create new runlevels and drag services from the Services pane into them. (Alternate runlevels may be specified by using the softlevel parameter on the kernel command line in Grub or Lilo.) Krcstat is a bit conservative and will not let you delete the boot or default runlevels or certain boot services deemed critical. To use its configuration features it must run as root; if you only want to monitor services, it can be run as a normal user.
mod-icon-geom is a command line utility that allows the user to set the KDE 4 desktop icon's height and width. It creates a configuration file by using the -c option along with default height (-h) and default width (-w) option settings. It modifies the geometry for each desktop icon found in .kde4/share/config/plasma-desktop-appletsrc to make the icons have the desired height and width. After the configuration file is generated, the user can modify that file to have height and width values for individual icons that are different than the default (useful if the icon text is larger than the default width allows), and the true values in the appletsrc file can be saved back to the configuration file with the -s option. This utility saves time and energy by giving the user an additional level of control over desktop icons that was lost in KDe 4.
