Hi @interpret-ml 1. Do you plan on adding staged prediction similar to [XGBoost's ntree_limit/iteration_range](https://xgboost.readthedocs.io/en/latest/python/python_api.html#xgboost.XGBClassifier.predict_proba)? 1. Do you plan on adding warm starts similar to [scikit-learn's GBM warm_start](https://scikit-learn.org/stable/modules/generated/sklearn.ensemble.GradientBoostingClassifier.html)? Thanks for your...
