Hi d-iivil, just want to mention that applying changes without reboot doesnt' work at all with me. Theme customizer says it would restart services but then I'm left with a broken GUI. Looks like desktop doesn't get started again. Fortunately the top menu still works and I can select shutdown or reboot.
Don't know whether it's related to special theme customizer settings/changes only or to some other installed apps. Do you know of similar issues?
