I think when Thea is intergated into SU etc it'll be a lot more user friendly, specially for the people who haven't got the time to get their heads around Studio's UI.
I had Byrce for four years before I actually tried to use it and thats got the weirdest UI in the world, but its not bad if you manage to figure it out, bit of a poor man's Vue lol
I think i adjusted quickly with thea's UI. At first its kinda confusing, but once you are getting the hand of it, you will find it actually as efficient. The drag and drop thingies are so much easy to do alongside those scrolling dials. Basically it has too many things to offer. I hope next time it will have inferencing capability when moving components to any plane,like Sketchup.
