Crap I just updated to Electrum 3 and forgot to do that shit, my fault
Even so, I don't really understand how the transaction is 3 Kb for a $10 value !!?! Can't you complain to someone about this ?
Yes, switching to dinamic fees is recommended to have more control on fees. But keep in mind Bitcoin is currently not viable to make cheap transactions of that small amount. Also your transaction was very large. Unfortunately it's not convenient to spend money which has so many inputs and it's usual to spend more in fees than in transaction. the best way is to just keep that money in your wallet and wait until (hopefully) scaling problems will be solved. For a better comprehension of fees, you can read this guide: http://bitcoinfees.com/
