Thanks for all the responses but no one has pointed me to a solution where bitcoin was back in the old days.
I don't get it, in the first version of Bitcoin, it's already using the same UTXO model.
The only thing that's changed is the amount of transactions that you've been receiving.
I literally send all my funds to ONE SINGLE ADDRESS yet each bitcoin app I have used INSISTS on changing my funds around causing me headaches and endless fees later.
-snip-
I want ONE BITCOIN ADDRESS FOR EVERYTHING ALL FUNDS!
I tried electrum too it does the same thing! I tried googling how to disable it, but mine doesn't have the option or I'm just having a hard time?
Okay, there's way to do that in Electrum

You do that by importing a single WIF private key to Electrum by selecting the option "
Import Bitcoin addresses or private keys" when creating a wallet.
Take note of the "
info" tooltip above it to indicate the address type.
But
take note that receiving everything to that single address nor receiving the change to that same address wont do any difference.
