There are many features in new MyEtherWallet make me difficult, like a we must refresh page when add a custom token. I didn't find eth gas station, so i must find it by searching manual. always low response and blank while i access in mobile phone. But its give me easily to setting transaction speed. There are 4 speed in transaction Economy,Regular,Fast and custom. And you can Import or Export your transaction speed
For me it was quite difficult to use because I had used the old interface for a long time, but I think only a few times I will easily use this new interface and of course it looks very nice and wonderful
