It's not an alternative but a companion, or if you prefer it only replaces the UI not the node ! But it is true that as a consequence, many users may not use the AE interface just because there will be no need to scroll the panel to access all requested attributes (including indigoShader.material), and it refreshes quickly.
Have I made myself clear, dear dev in chief ?
EDIT: I've remembered the right term: it's only a front-end.
