I like how easy it was to use once we got used to using our computer instead of paper maps! It's very user friendly so anyone can learn quickly what they need without having any training or experience in construction management/planning etc..
The only thing i dislike would be if there were different types of floors (ie office vs storage) but this could just mean adding another layer which isn't too bad at all since its already pretty customizable anyway. This program has really helped us out by being able to easily navigate through multiple storeys within one room as well as creating diagrams showing where things are located throughout an entire facility.
