I found that to delete a model in the new ide you have to first remove any impees associated with that model. It then is placed into the list of ‘Inactive models.’ If you then click the model from that list, you’ll be prompted to delete it.
Still searching for how to delete a dead impee though…
Right now there isn’t really a way to delete a dead/no longer used device (we call impees devices now, since imp/impee was someone what confusing).
The common solution around here is to create a dummy model with a name that will drop it to the bottom of your list (I use ‘zzz_Inactive’) and associate your dead/no longer used devices with that.
We have a task in our backlog for this functionality, so it will be coming in the future.
