Option C:
Your Sneak Attack is right on your hotbar on bindable possitions ... sure you can still forget it, technicaly, but its certainly a lot harder to forget press attack button you are using with every single character, than forget to go turn on some shining icon in the corner.
So you attack Goblin 1 and kill it regular way > you press 1/2/3 (depending on where you put your Sneak Attack you wish to use) and kill Goblin 2 aswell.
Smooth, simple, fast, effective, with fresh scent of lemons!

You can still have this option unchanged if they make it a charge that you can toggle...
Nothing would change for you in that department if you want to play like that you just leave the charge on/don't touch it for the rest of the game, simple.(a bad way to play you leave a lot of damage on the table...but that's a different topic )
The only thing it would change for you is that if you multiclass you could trigger sneak attack together with other attacks like Menacing Attack or Pushing Attack and so on you get the picture. OW and IF you missed with your attack you could sneak attack again with your other attacks meaning you could use that active icon - press 1 key more then once per turn.
Even if at that point the active icon is redundant, but it would force turn on the charge if you played with the toggle button and forgot to turn it on for whatever reason.
