When I first switched to Lightroom, I I struggled with the archaic, clunky, buggy, counter-intuitive import interface. Then, 2015.2 came out. The new import interface was clean, smooth, intuitive, and it actually worked! Then for reasons that I don't understand, 2015.3 reverted back to the ugly, buggy interface. Please bring back the new interface, or at least offer it as a preference. Many thanks!
Unfortunately we had a lot of users complaining about that interface and version of Lightroom, so we had to switch back to the old interface.
If you really want that interface you can install LR 2015.2 and never update it but i believe that is not a good idea, i also doubt that, Lightroom will ever get that interface.
