My guess (some if this we already have, some we don't): - automation: integration of heuristics (multiple columns that you can program via formulas and such) - exploration: finding outliers or most similar records given some reference (e.g. "I want to label more rows that are about business news in some extent") - monitoring - labelmanagement [which we don't offer yet in the extent we'd like to]: merging and splitting labels etc.

generally anything that scales and "somewhat" guarantees the users to input valid labels.

But it definitely offers something that new tools don't: users are super familiar with it.
