model names
If you train on top of a model, the model needs a new name. If you train on top of a model that has been trained on top of a model you are completely lost in which state you are because the old training report seems to get overwritten or continued but it is not clear which value is for what training. the easiest solution would be to give newly trained models new names or to let the user change the name of any model.
I thought I had already filed an issue on this and we have discussed it but I can't find it so I resubmit.
