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
Since its a new design, I still need time to make myself get used to it.
I still kind of a little confusing, usually i just access my wallet through the site using private key, and new i need to download an app to do it. but perhaps it would be safer than the old method.
