It seems the order of node number within each segment is reversed when I either "decompose to simple neuron-segments" or "edit this neuron". For example, going from the root to the terminals (centrifugally) the node number should increase (segment 1: -1<1<2<3<4; segment 2: 4<5<6; segment 3: 4<7<8). However after I decompose (which I assume is part of the edit function) and rejoin the segments, it becomes (segment 1: -1<4<3<2<1; segment 2: 1<6<5; segment 3: 1<8<7).

Also the rejoin function is much slower (>10 times) than the decompose function. Is this related to the reverse ordering of the node numbers?
