So you think I should put a tick next to ^ spend only confirmed coins ^ this will stop electrum trying to send out any unconfirmed low tx fee coins I will eventually receive? I dont need to use these and prefer to let them confirm before spending them. I don't want to mix them in the send with my confirmed coins.
Yes you can do that by selecting the "spend only confirmed coins" or disabling "spend unconfirmed "
You touch on an interesting point with coin control in electrum.
I have noticed that I set up a watch only wallet with electrum using only the import a single public address way.
This way it always sends my change to the same address that im sending from.
By default the coin control is hidden on electrum because generally
If you tend to spend or spend part of your coinfrom your inputs then you are spending all coin available in your wallet(as a single output) and receive a UTXO as a change from your spending
You can actually control how you want your coin to be spent
If you wish you use a view only wallet then you can choose to use it along with an airgapped device as a cold storage to sign your transaction for broadcast
