I'm not upset, frustrated is more like it. I can't be the only person that wants to be able to set appropriate manual fees. I'm sure the software must calculate the size of the transaction, why isn't this available to me? Is this a technical limitation of some sort?
You already know you can use 21.co to choose the level of fee appropriate to your priorities for a given transaction, it's written in one of your posts up the page.
You're finding things to complain about for the sake of complaining, not because you need help. That makes you a troll. Don't troll.
