Please add "to next" as an option for defining extents of extrusions. This is a normal option in competitor products and is indispensible in some situations. For example, extruding up to a non-planar face or one that isn't parallel to the sketch plane, particularly with a thin walled surface.
Without this option, the extrusion may emerge on the other side of the body before it has fully merged with the incident face. Without "to next" there is no easy work around.
