I created a hierarchy of models in the Models module (e.g Bones, Organs, Muscles). When I click a little too fast on a given model in a hierarchy, this sometimes results in the model moving up or down in the list of models (e.g. the Skull bone becomes listed in the Muscles hierarchy).

Would it be possible to add a lock function like in the Annotations/Markups module to lock the hierarchy of models at some point?
