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
I wasn't aware of the new design, but I have to check it out later. Those set fees are like other bitcoin wallet though, so its very easy to use in my opinion. Before we don't have that kind of settings before, but I'm wondering why need it though, since Ethereum transaction is very quick already. Anyways, for those newbies this might be a good help.
