Have not done much to change the default other than pin applications and use docky. Will probably continue to use docky for the time being. Got rid of some of the indicator stuff. Sound in particular since I remove all the pulse-audio stuff I can. The volume icon is provide by kmix, for which I created a kmix.desktop file with the contents of
and placed it in '~home/.config/autostart', I don't think the '--keepvisibility' part is necessary any more, I think it always starts in the state (visible or hiddent) it was in when it was last running.
Looks like some of the launchers must have been pick up from stuff I had added to the gnome panel, the area that appears to be a blank area in the icons is the launcher for xkill, which I don't remember adding, it did previously have an icon though.
EDIT: Forum access was bad when I tried to post this and it looks like the attachment didn't make it... tried adding it, but also including a link showing my desktop just in case.
