Version 4

I admit Firefly is a great tool, but the interface change from version 3 to version 4 was quite substantial and should probably result in someone possibly being admonished if not outright fired. The commands are so scrambled around, it makes previous tutorials almost useless. 
I know this first hand because I worked as a Software Engineer in Silicon Valley and we had to warn our designers sometimes, to be careful when making radical changes. (For example, hiding more common familiar commands deep in sub-menus that use to be front and center.)
At least from a common sense perspective, make a couple hour video that may follow the basics outlined in an older video. That should be a given. (Other companies, in the Valley, do that as part of their due diligence.)
