Is there any plugin or config switch that would change the color or the title of tabs with unsaved changes?

Unfortunately it isn't do anything if you use the Soda Dark.sublime-theme.
The new theme in 2.0.1 and up highlights the close button for tabs with unsaved changes.
Does on mine (haven't checked version) -- there's an orange dot on the tab indicating unsaved changes.
