I'm not sure that I agree. For every field, the old version went to the model 
and got a DiveObjectHelper from which it extracted the display data. What has 
changed is that now the string is extracted by the model itself and passed to 
QML. There should be the same number of model-lookups, just the strings being 
extracted at different levels.

I see no fundamental reason that the new version has to be slower and we 
should try to figure out what is happening.

Concerning redesign: Is there a reason that a ListView was chosen over a 
TreeView (which seems like the more logical choice to me)?
