Configurations is the main thing lacking from Fusion 360. It gets very frustrating having to have multiple versions of the same file and having to make sure to update each one to keep them all at the same level. I have't been using Fusion 360 for long but the inability to quickly create variations of a file is a huge let down and is the biggest reason why I am thinking of heading back over to Solidworks. It is a requirement in nearly all fields of designs to have slight variations on a base model.
