And probably there is nothing wrong to have separate node for each task. I'm not sure which problem this should solve? (filter mesh attributes?) As for vertices/edges/faces, as far as...

Two is certainly better than five. )) Any way this requires new version of the node or separate one. My opinion is that mask, ind_true, ind_false (probably even dataFalse) sockets...
