I'm a long time Creator user and I have been testing the new UI for a while now and I feel like 90% of the bugs have been fixed. However, based on my testing it seems that the new UI is about 2-3x slower! I love the new UI and and I'm willing to give up speed/performance for a more polished look. I'm curious if anyone else has seen the same results? 

Have you switched over the the new UI? If yes, do you have any issues? If not, what's holding you back? 

Thanks. Zalman
