Ok, is that possible in Electrum as well?

I am not sure if Coinomi supports mac. So I am thinking Electrum or Mycelium. I was thinking I am going to do it on my computer. Do you recommend doing it on a smartphone? And if so, why?

And which one would you choose of all the alternative wallets for a mac-user?

I've heard some of them does not support Bitcoin cash. Which ones do support it?

Also, how do you mean that I can set the fee myself? Like with a limit order or something? Do I just write down "zero fees" or something?

Thanks for the help
