I just wanted to make sure everything is OK, so I guess "peace of mind". And I did waste some money for two transactions, yeah. Paid dollar or two. I'll know better next time.
If you have an unconfirmed transaction in the future and you right click on that, you will see two options that will replace your transaction with a new one paying higher fee.
The "Increase fee" replaces the transaction with a new one paying higher fee and sending the fund to ame address as the original transaction.
The "Cancel (double-spend) replaces the transaction with a new one paying higher fee and sending the fund to one of your own addresses.
