I just upgraded to 4.x from 3.x but this new layout is kind of tough to use. Is there a way to get the 3.x layout? Or at least set a way for the contents of a folder to expand in the folder tree like it did in 3.x? Without that, I can’t see a way of dragging scripts onto prefabs.
Assuming you’re referring to the project view, use the project view tab menu to switch to 1-column view.
