The two corresponding apps Reminders and Notes can't be taken off of the dock by dragging. You can right click and remove them from dock, but every restart they appear. Would like to see a work around, since I won't be using them. Also for the battery there is no option for "Time". The only option is a check for show percentage by the battery icon, other wise it's just the battery icon that leaves a large space for the volume to be clicked.
