I think it has some pluses. When your browsing through a folder of models or textures, obviously its way better.
But alot of the time I am just jumping back and forth between folders dragging files around. I put all my stuff in heavily nested folders.
So now lets say I want to hook up 5 textures to a scene. Those 5 textures are all in different folders. Before I’d just expand each folder, drag them all in. Now I have to click the folder, then move my mouse over to the new file viewer window, click and drag it, then click the next folder, move mouse over to file viewer, click and drag, repeat. I am finding for general usage I am having to click far more and move my mouse far more than I had to with the 3.x project pane.
Is there some way to make files also be shown in the folder hierarchy of the project pane?
