I've had a lot of enjoyment in customizing environments in Black Dragon but the saving process is a mystery and I am struggling to find a simple 'here's where you save your own personal environments' online or in BD. I see Save to Disk (file)/Save as (item) and Apply Only to Myself. But nothing that indicates it's a user preset in the menu, which, somehow I created 3 presets that I want to add to. There must be some simple step I'm blowing past, any suggestions/pointers would be a huge plus. Thanks!
