I still use this feature, it comes under the "Task List" window. Adds any "TODO" comments in realtime by default but it's also possible to extend what tokens show up alongside "TODO" [0]. I've added "Hack" or "Perf" for temporary implementations that definitely can be improved but not necessarily critical.
