Would be really nice to be able to option drag to duplicate Advanced conditions. Sometimes you add for ex a bunch of the same condition and have to look again in the long list to find the same condition again. And its not alphabetical so it can really make you blind sometimes to find the same again. 
I remember you could quickly change so you could duplicate actions with option drag. Maybe it wont work since you use that to nest conditions?
If it doesnt work is would be nice to be able to right click and duplicate conditions. As I understand it you cant add for ex several app names in “active_app_name CONTAINS "Safari"“?
Just a thought of an improvement. As some times you do a long list with the same conditions.
