The current UI of system-config-services displays on the left the list of all the installed services, with a checkbox to chkconfig them on/off. It would be nice to color some of these lines (background), we could do : - green for the checked services which are running - red for the checked services which are stopped - normal for the others This should be pretty easy to do (well, I could even do it myself)
Don't bother at the moment as I want to revamp the UI quite thoroughly (bug #249204) and things will be in flux for a while.
The current s-c-services version indicates in each line whether a service is configured to be started and its status with two icons. I don't think marking the lines with colors is feasible as that might clash with themeing and isn't good for color-blind people.
