A nice feature would be selective model reload. When a single model is updated, to see the change, you must reload all models which takes time. Example, I have 25 models linked into a merged model. If one model updates Glue must reload all 25 files to see what has been updated in the one model. It would be nice if I could update only the model/models that have been updated. Loading 25 models to see one small change can be time consuming.
The same feature would be nice in the Navisworks environment.
