Agree - I have been using 5 for 3 months now everyday for work and still seem to be struggling not defaulting back to UE4 UI. I wish they offered an option to have either or 5 or 4. As soon as I open a UE4 product I am so happy to use the old UI, just feels faster. I keep hoping that I will get used to it and just to retrain myself but I am losing faith. I am forced to use 5 for work and converted over my projects so I am trapped now.
