I already have it planned for some time. Can’t promise when it’ll be done, it needs a lot of code changes. Cycling can’t be done using standard cursor movements keys; instead, I plan something as Alt-<, Alt-> or make it user configurable.
As for [n/m], both numbers have meaning. The first one is the number of symbol instances found (overloaded function, methods etc.) and the second is number of definitions found for current instance (if you have for example static function with the same header defined in several files, there will be multiple definitions in BSC database).
