Simplify interface insertion
Interfaces are awkward to place in a model.
You have to place the round-end first and then haphazardly try to connect to it with an association.
It would be far better to simply plus the whole lollypop in one go.

This is a wonderful app.
But then there are areas that are unnecessarily unwieldly for no apparent reason.
However great work guys - keep it up.
