One nice feature of menu bars is their capability of grouping different items using a separator.
Having ring controls with many text entries it would be nice from a user perspective if these many entries also could be grouped using one or more separators.
What would be also convenient is the ability to dim or hide a specified entry; right now it is possible to rebuild the ring programmatically with one or several entries less (or more), but this is some overhead that could be minimized by simply hiding or showing an indexed entry.
